Update: They're hitched! The couple married at her Montecito home in what People.com calls "a classic, simple, very pretty, garden-inspired wedding."
Congrats are in order for Drew Barrymore!
On Saturday evening, the expecting star will tie the knot with fiancé Will Kopelman in Santa Barbara, Calif., People.com reports.
Barrymore kicked off her wedding weekend with a 100-guest rehearsal dinner at Montecito's San Ysidro Ranch, a luxury wine-country hotel on Friday night.
People reports that best pal Cameron Diaz and Jimmy Fallon, along with his wife Nancy Juvonen, were present.
Drew Barrymore is expected to walk down the aisle in a Chanel gown. She and Diaz were spotted at the designer boutique in Beverly Hills for a fitting earlier this week.
