Jemima Kirke has officially called it quits with her husband of seven years, Michael Mosberg. A source tells Us Weekly that the 31-year-old "Girls" actress and the former lawyer decided to separate in the summer of 2016.

Mosberg was on the exclusive, members-only dating app Raya back in July, another source reveals to the webloid. The app is a favorite among celebrities like John Mayer, Jeremy Piven, Chelsea Handler and Matthew Perry.

It's unclear why they decided to separate. Last year in February, Kirke revealed in an interview with The Telegraph that Mosberg, who has set up a rehab center in Brooklyn, was concerned about the fact that she had began drinking again socially.

"Mike was nervous at first. He said, 'Look, I would never tell you what to do; you are an adult - just don't f**k it up.' He had every right to be scared, he knew my story," the British actress said. "But I was a different person back then. I was in my early 20s. I didn't have children."

Kirke and Mosberg first met when she was doing a rehab stint in her 20s. The two tied the knot in 2009. The former couple shares two kids together, a six-year-old daughter Rafaella and a son named Memphis, 4. Mosberg has two other children from his previous relationship.
