Jodie Sweetin, the former 'Full House' star who played precocious Stephanie Tanner, is separating from her third husband, Morty Coyle, just after more than a year of marriage, citing irreconcilable differences, TMZ reported.

Sweetin filed for divorce in a Los Angeles court on Monday.

"She seems in good spirits," a source told Us Weekly. "She's sober still so she's in way better shape than last time. It's definitely true. I guess it's not working out."

News of the divorce comes just a few months after the couple made it public that they got married in March 2012. They wanted to wait till their first anniversary to announce the news to the world, the couple had said at the time.

According to legal documents cited by TMZ, Sweetin wants full custody of their two-year-old daughter, Beatrix. The former actress is also asking for ownership of their 2000 Toyota Avalon, and she wants Coyle to split their $200 Kohl's credit card balance.

Sweetin was earlier married to a Los Angeles Police Department officer Shaun Holguin and later to Cody Herpin, a transportation coordinator, with whom she has a five-year-old daughter, Zoie.

Sweetin has had her share of personal problems ever since her successful stint on the sitcom ‘Full House’ wound up in 1995. She has struggled with drug and alcohol abuse, and has made repeated trips to rehab centers in an attempt at sobriety.

Sweetin’s memoir, ‘unSweetened,’ published in 2009, is a detailed account of her struggles with drugs and alcohol. In the book, Sweetin explains that one of the events that prompted her to change her lifestyle was when she drove drunk with her baby daughter in the car.

"That was the big rock bottom. I had two glasses of wine and drove with her in the car. I not only put myself in danger, but also my daughter, who I loved more than anything. I felt terrible."
