The former Full House star was surprised by her boyfriend, Morty Coyle, when he popped the question at her 29th birthday party Tuesday in Los Angeles. "It was a complete surprise," Sweetin told the magazine. "We are just thrilled and I am in shock still!"
Coyle proposed to Sweetin with a ring featuring a 2.5 carat oval sapphire surrounded by 18 diamonds. A wedding date has not been set.
Sweetin and Coyle have a 5-month-old daughter, Beatrix. Sweetin also has a 2-year-old daughter, Zoie, with ex-husband Cody Herpin. Sweetin was also previously married to Shaun Holguin for four years.
In 2009, Sweetin released unSweetined, a memoir chronicling her years of alcohol and drug abuse following the end of Full House's run.
