Drew Barrymore and longtime love Will Kopelman exchanged vows Saturday in “a classic, simple, very pretty, garden-inspired wedding," an insider tells People magazine. Barrymore, who is pregnant with her first child, wore a custom Chanel gown. Kopelman, an art dealer, sported a black suit and grey tie.

The Jewish ceremony, planned by Yifat Oren and Stefanie Cove, was held at Barrymore’s Montecito, California home. Guests included Reese Witherspoon and husband Jim Toth, Cameron Diaz, Scarlett Johansson, Jimmy Fallon and wife Nancy Juvonen, and Steven Spielberg.

Barrymore, 37, and Kopelman began dating in early 2011 and announced their engagement in January 2012.

Barrymore most recently starred opposite John Krasinski in Big Miracle.
