Kirke, who fans know best as her Girls character Jessa Johansson, wed Mosberg, a former lawyer, in 2009. They share two children together: daughter Rafaella Israel and son Memphis.
The couple met when Kirke was in her 20s, during a stint in rehab for “everything … partying,” the actress told the Telegraph last February.
At the time of the interview, she told the publication that Mosberg was in the process of setting up a rehab center, The Hook Recovery Center, which is set to open this year in Red Hook, Brooklyn. Kirke also said that she had started drinking again, socially — a decision about which her estranged husband was initially worried.
“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,” she told the Telegraph. “But I was a different person back then. I was in my early 20s. I didn’t have children.”
