Movie Title? Waking up Married?

Okay, I think this is a recent movie (like 1 year), I thought it starred the girl who played Donna on That 70s show, but cant find it on IMDB. She is in Mexico to get married and she wakes up the next morning married to another man and can't remember anything. They backtrack and find out her husband cheated on her and she drank tequila all night. He's an artist. Anyone know?
