What happens in Vegas doesn't necessarily stay in Vegas! Francesca Eastwood, Clint Eastwood's 20-year-old daughter, took the plunge in Sin City over the weekend and got married -- to Jonah Hill's brother Jordan Feldstein, a source confirms to Us Weekly. (TMZ was first to report the surprise nuptials.)

The two filed a marriage license with the Clark County Recorder's Office and tied the knot on Sunday, Nov. 17. Per TMZ, they exchanged vows at the Simple Wedding Chapel in Las Vegas.

A source tells Us the coupling is a fairly new one. "They haven't even been dating that long, but when in Vegas!" the insider says of Eastwood and Feldstein, who manages Adam Levine, Maroon 5, and Robin Thicke.

Model and actress Eastwood, who starred on the reality show Mrs. Eastwood and Company with her stepmom, Dina Eastwood, was previously in a long-term relationship with celeb photographer Tyler Shields. In January of this year, as part of her "25 Things You Don't Know About Me," she told Us that Shields was "the love of [her] life." See more photos of the model here.

"We've been together two years and met doing a photo shoot together," said the star, whose mother is Titanic actress Frances Fisher. "I have some gifts from Tyler that I always have [with me]. My stuffed animal Nino, my bear, is my lucky thing."

The 2013 Miss Golden Globe also revealed she wanted to someday tie the knot. "I have a tattoo of a circle on the middle finger of my left hand that I'm getting removed," she told Us. "I hate it because I want to get married one day and I don't want the tattoo next to my wedding finger."
