Troubled FULL HOUSE star JODIE SWEETIN splits from Hubby #3.

Sweetin, 31, married Morty Coyle in March 2012 and had one child together, daughter Beatrix Carlin Sweetin-Coyle, who is two, RadarOnline reported.

Sweetin is seeking full custody of their daughter.

As the ENQUIRER previously reported, Sweetin — she has battled an addiction to cocaine and crystal meth in the past — got engaged on her birthday to Coyle when he presented her with a 21.2-carat oval sapphire ring, surrounded by 18 diamonds.

She also has a five-year-old daughter Zoie with her second ex-husband, Cody Herpin, a  transportation coordinator in July 2007 but they separated just a year later.

After a nasty divorce battle, they were granted joint custody of their daughter in April, 2010.

Jodie’s first marriage was to police officer Shaun Holguin when she was 20.

That marriage ended four years later.
