Donnie Wahlberg and Kimberly Fey married on August 20, 1999. They filed for divorce on August 13, 2008, citing irreconcilable differences.

What band does Xavier Alexander Wahlberg play in?
Xavier Alexander Wahlberg plays in Upon Stone, a Los Angeles melodic death metal band, where he serves as vocalist and bassist. Upon Stone is based in the San Fernando Valley area of Los Angeles, California. The band's lineup, as described in Century Media label material, includes Xavier Alexander Wahlberg on vocals and bass, Wyatt Bentley on drums, and Ronny Marks on guitar. Century Media describes Upon Stone as a San Fernando Valley quartet, which points to a four member lineup, while the named members in label material cover three roles.
Upon Stone grew out of teenage music projects in the San Fernando Valley, in bands fuelled by classic Gothenburg and Finnish metal acts. Donnie Wahlberg said on a talk show that Xavier Alexander Wahlberg was already showing a passion for death metal at age 17. Upon Stone released Dead Mother Moon, its Century Media debut album, produced and mixed by Taylor Young, known for work with Drain and Suicide Silence.
What kind of music does Upon Stone play?
Upon Stone plays melodic death metal, or melodeath, with hardcore roots. Melodic death metal is a subgenre of death metal that pairs harsh vocals and fast, aggressive guitar work with melodic guitar lines drawn from early 1990s Scandinavian metal. Upon Stone draws on the Gothenburg sound, a style named for the Swedish city where bands such as At The Gates and In Flames shaped the genre, and on Finnish melodic death metal, a style known for dark melody and driving rhythm.
Century Media describes Upon Stone as delivering a uniquely visceral, unfiltered energy, with a passion for the earliest melodeath influences, including At The Gates, In Flames, and Dissection. As vocalist, Xavier Alexander Wahlberg delivers the harsh vocal lines that define death metal. As bassist, Xavier Alexander Wahlberg anchors the low end that keeps fast guitar work grounded. Donnie Wahlberg rose to fame in New Kids on the Block, a pop group built on harmonies and mass appeal, while Xavier Alexander Wahlberg works in a genre built on intensity and a smaller, loyal audience.
What is known about Xavier Alexander Wahlberg's net worth?
Xavier Alexander Wahlberg's net worth has not been publicly disclosed. No verified earnings report, no tax record, and no interview gives a confirmed net worth figure for Xavier Alexander Wahlberg. Readers should treat any single number for Xavier Alexander Wahlberg's net worth as an estimate, not a fact. Some profiles publish an estimate of around one million dollars, sometimes presented as a combined estimate for Xavier Alexander Wahlberg and his brother Elijah. Those profiles cite no earnings source, no album sales figure, and no tour revenue figure to support the number.
The confusion often comes from family wealth. Donnie Wahlberg's net worth is reported in some profiles at around 20 million dollars, based on his long career in music, film, and television. That figure, even where reported, belongs to Donnie Wahlberg, not to Xavier Alexander Wahlberg. Family wealth does not transfer automatically to adult children, and Xavier Alexander Wahlberg has built an independent music career with its own income pattern, based on album releases, live shows, and merchandise. A fair summary is short: his income comes from music, his net worth is not publicly disclosed, and any precise figure online is unverified.
Is Xavier Alexander Wahlberg married, and does he use social media?
Xavier Alexander Wahlberg has no confirmed public marriage, and no verified public social media account. Profiles that cover his personal life state that his relationship status is unknown, or that he is believed to be single, because no public record confirms a partner, a marriage, or a child. That wording matters: "believed to be single" is not the same as "confirmed single", and "no public record" is not the same as "no private life". Xavier Alexander Wahlberg has a private life, and he has chosen to keep it private.
Xavier Alexander Wahlberg has no verified social media presence under his full name, and profiles consistently note that he is not active on social media. Fans who find accounts using his name should treat those accounts as unverified. Upon Stone has label and streaming pages, and those pages are the reliable route to the band's music. Donnie Wahlberg shared a rare Father's Day Instagram post in 2019 with Xavier Alexander Wahlberg and Elijah Hendrix Wahlberg, from Donnie Wahlberg's account, not from Xavier Alexander Wahlberg.
How does Xavier Alexander Wahlberg differ from his brother Elijah?
Xavier Alexander Wahlberg and Elijah Hendrix Wahlberg are brothers, musicians, and opposites in sound. Xavier Alexander Wahlberg, born in 1993, plays melodic death metal with Upon Stone in Los Angeles. Elijah Hendrix Wahlberg, born in 2001, fronts Pink Laces, a band described in music reporting as an indie and synth pop project, with Elijah Hendrix Wahlberg as frontman. The age gap is eight years, and the genre gap is wider still: death metal on one side, indie pop on the other.
The brothers also differ in public visibility. Elijah Hendrix Wahlberg has a clearer public profile through Pink Laces, while Xavier Alexander Wahlberg has a narrower profile, tied to Upon Stone and label material. The confusion between the brothers is common in quick profiles. Readers can avoid that error with one check: Upon Stone belongs to Xavier Alexander Wahlberg, and Pink Laces belongs to Elijah Hendrix Wahlberg.
What do most profiles get wrong about Xavier Alexander Wahlberg?
Most profiles about Xavier Alexander Wahlberg repeat the same quick facts table, and they repeat the same errors with it. The first error is net worth: profiles present an estimate as a fact, with no source. The second error is marriage: profiles present a guess about a partner as a fact, with no public record. The third error is band history: profiles name Upon Stone, but give no album, no label, and no bandmates, so readers learn a band name and nothing about the music. The fourth error is family mixing: profiles blur Xavier Alexander Wahlberg with Elijah Hendrix Wahlberg, or blur Xavier Alexander Wahlberg with his father, so readers leave unsure who played in which band. A fifth error is freshness: many profiles carry an old age, with no update date that matches the current year. A profile that says Xavier Alexander Wahlberg is 32 in late 2026 is out of date, because Xavier Alexander Wahlberg turned 33 in March 2026.
Content gaps that shape this article: Upon Stone music detail, including album Dead Mother Moon, Century Media label, producer Taylor Young, and bandmates Wyatt Bentley and Ronny Marks; brother separation, with a clear Upon Stone versus Pink Laces check; net worth honesty, with family wealth kept separate; confirmed versus unconfirmed claims, with partner status and school names marked unverified; and freshness for late 2026, with age 33 and Upon Stone album detail updated for October 2026.
Why does Xavier Alexander Wahlberg stay private?
Xavier Alexander Wahlberg stays private because his career does not need public fame to work. Metal bands build audiences through albums, live shows, and word of mouth in a scene, not through celebrity news. Xavier Alexander Wahlberg can tour, record, and release music with Upon Stone while keeping his home life, his relationships, and his daily routine out of public reporting. That model fits metal culture, where fans judge a band by its sound, not by its singer's family tree.
Privacy also protects a normal life. Xavier Alexander Wahlberg grew up as a celebrity child, with a father in a famous pop group and uncles in film and television. A public feed or reality show role would pull Xavier Alexander Wahlberg back into the celebrity frame he stepped away from as a teenager. Donnie Wahlberg speaks about pride in his sons' bands, and stops short of sharing details his sons have not shared. Privacy does not mean absence: Xavier Alexander Wahlberg is present in music, in label material, and in album credits.
Conclusion
Xavier Alexander Wahlberg is a musician, born on March 4, 1993, in Los Angeles, California, and the eldest son of Donnie Wahlberg and Kimberly Fey. Xavier Alexander Wahlberg plays as vocalist and bassist in Upon Stone, a Los Angeles melodic death metal band with a Century Media debut album, Dead Mother Moon. Xavier Alexander Wahlberg keeps his private life out of public view, has no verified social media presence, and has no publicly disclosed net worth. Xavier Alexander Wahlberg differs from his brother Elijah Hendrix Wahlberg, who fronts Pink Laces, and differs from his father, whose pop and acting career built the family name. For readers, the clear takeaway is this: judge Xavier Alexander Wahlberg by his music, not by his surname.
