Drew Barrymore Marries Will Kopelman

Actress is pregnant with her first child.

Drew Barrymore wed her fiancé of five months, art consultant Will Kopelman, at her Montecito, California, home on Saturday.

Guests included Reese Witherspoon and her husband Jim Toth, Cameron Diaz, Jimmy Fallon and wife Nancy Juvonen and Busy Phillips and her husband. Barrymore and Kopelman were married under a chuppah at her home, and a rabbi officiated. It was "a classic, simple, very pretty, garden-inspired wedding," a source told People magazine.

Barrymore, who is also pregnant with her first child, was previously married to MTV personality Tom Green, and she had a monthlong union with Jeremy Thomas. The actress has also been linked to Justin Long and Strokes drummer Fabrizio Moretti in the past.

The couple, who have been dating since February 2011, reportedly got engaged early this year in Sun Valley, Idaho, where they vacationed over Christmas and New Year's. Kopelman reportedly asked the actress to marry him with a colorless, radiant-cut diamond ring designed by Graff.

In the September 2010 issue of Marie Claire, Barrymore opened up about her philosophies on love. "I'm happy to say that, at 35 years old, I feel I know less than ever," she said. "But in a liberating way. I'm trying to figure out how to make relationships work. The only thing I know is that there aren't any rules. There should be no infrastructure on how a couple is supposed to work. Life isn't like that."
