Todd Morgan And Rosanna Arquette

Introducing Mr. and Mrs. Todd Morgan! Two years after saying "yes" to her investment banker boyfriend's proposal, Pulp Fiction actress Rosanna Arquette said two other very important words: "I do."

"Rosanna Arquette and Todd Morgan were married in a private family ceremony in Malibu on Sunday," a rep for the Desperately Seeking Susan star tells Us Weekly exclusively. "Todd Morgan is the CEO of Belair investments and a philanthropist. Arquette has recently been seen in Girls and Ray Donovan. She is directing her first feature and has 3 TV shows in development. They are very happy." A source tells Us that celeb guests included Barbra Streisand.

The thrice-divorced actress -- whose three siblings David, Patricia, and Alexis Arquette are also well-known actors -- got engaged to Morgan in June 2011. "She's completely in love and had no hesitation in accepting," a source told Radar Online at the time. "Rosanna is, at the heart of it, a real romantic."

Indeed, Arquette told the Huffington Post in 2012 that while it was difficult for her to find a work/life balance, she didn't feel complete without a partner.

"I think, for me, it's been quite a challenge to have both. I was in a relationship for a few years and didn't work for a few years, and now I'm starting to go back to work and I am in a relationship," she said. "It's always about accepting the other person -- who they are and what they do. I love to work and I love my partnership, but I really do need both. If I'm only focusing on one, then I'm not a whole person."

This is the fourth marriage for Arquette. She was previously wed to director Tony Greco (from 1979 to 1980), to composer James Newton Howard (from 1986 to 1987), and to restaurateur John Sidel (from 1993 to 1999). She and Sidel have a teenage daughter, Zoe.
