The Charlie's Angels star will reportedly wed art consultant fiance Will Kopelman on Saturday evening (02Jun12) in Montecito, California and 70 guests, including her close pals Cameron Diaz and comedian Jimmy Fallon, are in the coastal town to celebrate with the bride-to-be.
Sources tell E! News that those who made the trip to Montecito for the alleged rehearsal dinner on Friday were gifted a basket full of local delicacies, including wine, olives and chocolate truffles.
The nuptials will take place at a private residence, according to reports, and will be overseen by celebrity wedding planner Yifat Oren, who masterminded Reese Witherspoon and Molly Sims' big days last year (11).
Barrymore, 37, was previously married to bar owner Jeremy Thomas in 1994 and comedian Tom Green in 2001. Both unions lasted less than five months.
