Who Is Xavier Alexander Wahlberg?
Xavier Alexander Wahlberg is an American musician and the first son of Donnie Wahlberg and Kimberly Fey. His family connection initially attracted public interest, but Xavier has developed his own identity in music. He performs as a vocalist and has also played bass for Upon Stone, a California melodic death metal band. Unlike his father, whose career includes pop music, television, and film, Xavier works within a much heavier musical scene. He also keeps a much lower public profile. Donnie has acknowledged that his older son prefers not to have his personal life discussed publicly.
Xavier Alexander Wahlberg’s Age and Early Life
Xavier was born on March 4, 1993, making him 33 years old in 2026. He arrived when Donnie Wahlberg was 23 and already experiencing major fame through New Kids on the Block. Donnie later explained that becoming a father changed his priorities and made providing for his son more important than thinking about his own legacy. Xavier spent much of his childhood outside the intense publicity surrounding his father. Details about his early home life are scarce, but his interest in heavier forms of music developed when he was young and eventually became a serious creative pursuit.
Who Is Xavier Alexander Wahlberg’s Father, Donnie Wahlberg?
Xavier’s father, Donnie Wahlberg, has spent decades in entertainment. He became famous as a member of New Kids on the Block, the hugely successful pop group that rose to international prominence in the late 1980s and early 1990s. Donnie later established himself as an actor, most notably playing Danny Reagan throughout the long-running television drama Blue Bloods. He subsequently reprised the character in Boston Blue. Despite his highly public career, Donnie has generally avoided placing his sons at the center of his celebrity image. He has instead spoken selectively about fatherhood and their shared interest in music.
Who Is Xavier Alexander Wahlberg’s Mother, Kimberly Fey?
Xavier’s mother is Kimberly Fey, Donnie Wahlberg’s former wife. Fey had professional ties to the music industry, and PEOPLE reports that she and Donnie began dating in the early 1990s after she worked on a New Kids on the Block album. Their relationship began before Xavier was born in 1993. The couple later married and welcomed another son, Elijah. Compared with her former husband, Fey has maintained a much less public profile. Reliable information about her present-day activities is limited. Her connection to the music world, however, means Xavier grew up with both parents having experience related to the industry.
Donnie Wahlberg and Kimberly Fey’s Relationship
Donnie Wahlberg and Kimberly Fey began their relationship during the early 1990s. Their first child, Xavier, arrived in March 1993. The couple married in 1999 and welcomed their younger son, Elijah, in August 2001. Their marriage eventually ended after several years together. PEOPLE reports that Donnie and Kimberly announced their separation and filed for divorce in 2008. The divorce was finalized two years later. The same source reports that they remained friendly following their separation. Although their relationship attracted attention because of Donnie’s celebrity status, both parents have generally kept details involving their sons relatively private.
Xavier Alexander Wahlberg’s Brother, Elijah Hendrix Wahlberg
Xavier has one younger brother, Elijah Hendrix Wahlberg, who was born in August 2001. Interestingly, both brothers eventually developed careers connected with music, although their styles are different. PEOPLE reports that Elijah formed a band called Pink Laces and has shared parts of his musical work publicly. Xavier took a heavier route through the metal scene with Upon Stone. Their musical interests also continue a family connection to the industry established by their father. Still, neither brother has followed Donnie’s career exactly. Xavier, in particular, has chosen a musical environment far removed from the polished pop sound associated with New Kids on the Block.
Growing Up in the Famous Wahlberg Family
Being Donnie Wahlberg’s son placed Xavier inside one of America’s best-known entertainment families. Donnie achieved fame in music and acting, while Xavier’s uncle Mark Wahlberg built a major career in film and entertainment. Yet Xavier has not relied on frequent celebrity appearances to create his own public identity. Instead, his documented work has developed within metal and hardcore circles. His musical choices also show that belonging to a famous family did not mean following the same creative formula. While the Wahlberg name naturally brings attention, Xavier’s work with Upon Stone is rooted in a specialized scene with its own influences, audiences, and musical traditions.
Xavier Alexander Wahlberg’s Relationship With Donnie Wahlberg
Music provides a clear connection between Xavier and his father, even though their preferred genres are very different. Donnie has spoken publicly about discussing music with his older son and has acknowledged Xavier’s desire to stay outside the celebrity spotlight. During an appearance on Rachael Ray, Donnie even avoided saying Xavier’s name while talking about his son’s band because he knew Xavier valued privacy. PEOPLE has also reported that Donnie rarely posts about either of his sons for that reason. His comments suggest a father-son relationship in which Xavier’s boundaries are taken seriously while their mutual interest in making music provides common ground.
Xavier Alexander Wahlberg’s Music Career
Xavier has developed a genuine career in heavy music rather than simply having a casual interest in the genre. He is best documented as the vocalist and bassist of Upon Stone, a melodic death metal group from California’s San Fernando Valley. His musical roots go back further than the band’s formal creation. Century Media’s official material says Xavier, drummer Wyatt Bentley, and guitarist Ronny Marks had played together in different projects since their teenage years. Upon Stone later emerged as a serious project and released its first EP, Where Wild Sorrows Grow, in 2021 before moving toward a larger record-label partnership.
Xavier Alexander Wahlberg and Upon Stone
Upon Stone gave Xavier his clearest professional identity outside the Wahlberg family. The group developed during the pandemic era and released the four-song EP Where Wild Sorrows Grow in 2021. It later signed with Century Media Records and released Dead Mother Moon on January 19, 2024. On that album, Xavier is credited on vocals and bass alongside guitarists Gage Goss and Ronny Marks and drummer Wyatt Bentley. The nine-track record also includes a guest appearance by Shadows Fall vocalist Brian Fair on “Paradise Failed.” The release established Upon Stone as a serious melodic death metal act with an international label behind it.
Xavier’s Musical Style and Metal Influences
Xavier’s music is much heavier than the pop material that first made his father famous. Upon Stone works mainly in melodic death metal, drawing strongly from the Scandinavian metal sound of the 1990s. Century Media specifically connects the band’s background to groups such as Children of Bodom, In Flames, Dissection, and At the Gates. The result combines aggressive vocals, heavy riffs, melody, and elements influenced by hardcore music. Xavier contributes much of the band’s vocal intensity while also having performed on bass. This musical direction has allowed him to establish an artistic identity that is clearly separate from Donnie Wahlberg’s pop and entertainment career.
Xavier Alexander Wahlberg’s Personal Life and Privacy
Very little verified information is available about Xavier’s romantic life or other private matters. That absence appears consistent with his long-standing preference for staying outside mainstream celebrity coverage. Donnie Wahlberg has publicly indicated that Xavier does not like being discussed on television, and PEOPLE notes that Donnie rarely shares his sons online because he respects their privacy. Consequently, claims about Xavier’s wife, marriage, home life, or personal finances should not be presented as established facts without reliable confirmation. His public identity is much easier to document through his music. This distinction is important because many celebrity-focused websites repeat personal claims without providing dependable sourcing.
Where Is Xavier Alexander Wahlberg Now?
As of 2026, Xavier remains most clearly associated with heavy music and Upon Stone rather than Hollywood celebrity culture. The band’s Dead Mother Moon marked an important career milestone when Century Media released it in 2024. Xavier’s documented musical activity has also extended beyond the simple label of “celebrity son,” with specialist metal sources recording additional performances and collaborations. At the same time, he continues to maintain a limited mainstream public presence. There is no need to fill those gaps with speculation. What can confidently be said is that Xavier has turned a teenage interest in heavy music into substantial recorded work within the metal scene.
Conclusion
Xavier Alexander Wahlberg may have been introduced to the public as Donnie Wahlberg’s eldest son, but his adult story is increasingly about music of his own. Born in 1993 to Donnie and Kimberly Fey, Xavier grew up connected to a famous entertainment family while maintaining unusual privacy. Instead of pursuing mainstream acting or pop celebrity, he entered the metal scene and became known for his work with Upon Stone. The band’s releases, including Dead Mother Moon, provide clear evidence of his professional path. Xavier’s story therefore combines a famous family background with an independent musical identity and a strong preference for keeping his personal life private.
