Margaret Qualley's Rep Denies Infidelity Rumors Following Jack Antonoff Split

Margaret Qualley's publicist called cheating rumors surrounding her split from Jack Antonoff 'categorically untrue.'

A representative for actress Margaret Qualley issued a public denial on Friday, July 10, pushing back on rumors that infidelity caused her marriage to musician Jack Antonoff to end. The rep's full statement, confirmed by Us Weekly, reads: 'The narratives running in the press about Margaret and Jack are categorically untrue. There are no trust issues. There was no infidelity or anything outside of…' The denial was also reported by TMZ and Just Jared. The statement is a direct response to circulating tabloid narratives attributing the breakdown of the relationship to cheating — a claim Qualley's team is actively contesting through official channels. Neither outlet provides details on when the separation was first announced or how long the marriage lasted. Antonoff is a prominent record producer known for his work with artists including Taylor Swift and Lana Del Rey; Qualley is an actress recognized for roles in films such as 'The Substance' and 'Once Upon a Time in Hollywood.'

Why it matters

Public denials of this kind are relatively uncommon and suggest the infidelity rumors had gained enough traction to warrant an official response from the actress's team.

Neither source indicates what further statements, if any, either party may make regarding the separation.

Key facts

• Qualley's rep issued a statement on Friday denying infidelity claims
• The statement described cheating narratives as 'categorically untrue'
• The rep specifically stated there were 'no trust issues' in the marriage
• Both TMZ and Just Jared reported the denial, sourced to Qualley's representative
• Neither outlet named the origin of the infidelity rumors or cited a specific incident

Bias & framing notes

Both outlets report the same core fact — an official rep statement — making the denial itself reasonably verified. However, neither source provides details about the underlying infidelity rumors, who spread them, or any corroborating context about the split. The underlying claim being denied remains unverified and single-sourced to unnamed gossip narratives. Coverage is largely consistent across the two outlets, with no significant framing differences.
