Jodie Sweetin, known to millions of TV fans as Stephanie Tanner on Full House, has filed for legal separation from her third husband, Morty Coyle, 15 months into their marriage.

The 31-year-old actress cited irreconcilable differences as the reason for the split. Sweetin put June 12 as their date of separation, according to documents filed last Wednesday in L.A. Superior Court and obtained by E! News

Sweetin is asking for primary physical and legal custody of their 2 1/2-year-old daughter together, Beatrix Carlin Sweetin-Coyle, with visitation rights for Coyle on alternate weekends.

According to TMZ, Sweetin also wants their 2000 Toyota Avalon and is asking that they split their $200 Kohl's credit card balance. 

On the day she reportedly filed for separation, Sweetin tweeted: "Hope you are all having an awesome Monday! A new week, a new beginning :)." 

The couple said their I-dos on March 15, 2012.  

This was the actress' third marriage. She is also mom to 5-year-old daughter Zoie with ex-husband, Cody Herpin. Her first marriage to Shaun Holguin lasted from 2002 to 2006. 

In her 2009 memoir, unSweetined, the actress revealed her past addiction to meth and alcohol, admitting she began using methamphetamine after Full House wrapped, because she was "bored". In her book, she chronicles her downward spiral of alcohol and drug abuse.

In one passage of the book, Sweetin discusses breaking into tears while addressing a crowd at Wisconsin's Marquette University about growing up on television and about how much her life had improved since getting sober - all while coming down from a two-day bender of methamphetamine, cocaine and ecstasy.
