Will Arnett is reportedly in a new relationship with supermodel Carolyn Murphy after ending his long-term partnership with Alessandra Brawn, according to multiple published reports.
People reported that the 55-year-old actor and comedian quietly called it quits with Brawn late last year. Arnett and Brawn share a five-year-old son, Denny, and a source told the outlet the former couple "remain committed co-parents".
The Sun reported that Arnett and Brawn split earlier this year. It is not clear when Arnett and Murphy, 51, began seeing each other, but the pair were reported to have appeared together at Sean Hayes' West End production of Good Night Oscar last month, where they were said to have looked "suspiciously like a couple." Daily Mail reported the sightings and said it reached out to representatives for Arnett, Murphy and Brawn via Instagram for comment but did not immediately receive a response.
Arnett is best known for his television work, including the sitcom Arrested Development and roles in animation and streaming projects. Murphy has had a long career in modeling and has been a fixture in fashion and advertising for decades.
Published reports offer differing timelines for the end of Arnett's relationship with Brawn. People characterized the split as having occurred late last year and described the former partners as cooperative about parenting. The Sun's account placed the breakup earlier in 2025. None of the outlets cited an official statement from Arnett, Murphy or Brawn confirming the reports.
The reports come amid increased public interest in the private lives of high-profile performers, but the available coverage is based on unnamed sources and appearances at public events rather than direct confirmations from those involved. Representatives for the individuals named were contacted by at least one outlet and did not provide immediate comment, according to the coverage.
