Cameron Diaz Squeezes In Last Minute Meeting Before Drew Barrymore's Wedding Weekend!

There are only a few days left until her BFF Drew Barrymore ties the knot, so Cameron Diaz is working overtime!

The My Best Friend's Wedding star looked lovely in a sexy all-white ensemble paired with some killer wedges, as she pulled her black Maserati up to an office building in Century City, on Thursday afternoon.

Cam was seen accompanying the pregnant actress to her final wedding dress fitting at Chanel in Beverly Hills on Wednesday, and a source tells Us Weekly: "Drew has been leaning on Cameron a lot. Cameron has been very involved."

The Charlie's Angels costars are so close, in fact, that Drew's fiance Will Kopelman gave her a heads up that he was proposing! "I knew Drew was getting married before she did," Diaz told InStyle UK.

Barrymore is set to walk down the aisle for the third time this weekend in an intimate ceremony at her estate in Montecito, California. Congrats!
