The actress exchanged vows with musician Morty Coyle in Beverly Hills, Calif. on March 15, 2012, but the union was only made public this April -- and now it is over.

Sweetin has filed legal documents in Los Angeles, citing irreconcilable differences for the split, according to TMZ.com.

The actress is demanding full custody rights of the pair's two-year-old daughter, Beatrix, and the family's Toyota Avalon car.

Sweetin has a five-year-old daughter, Zoie, with second husband Cody Herpin. She was also married to Los Angeles Police officer Shaun Holguin, but that union ended in divorce in 2006.
