Drew and Diaz's wedding dress shop
Cameron Diaz accompanied best friend Drew Barrymore to her wedding dress fitting, sparking rumours she will be a bridesmaid on the big day.
The Charlie's Angles stars were pictured leaving the Chanel store in Beverly Hills, where Drew had her gown tweaked ahead of her wedding to art consultant Wil Kopelman at her estate in Montecito, California this weekend.
Cameron revealed to InStyle magazine that Will asked her advice before his proposal to Drew last December, saying: "I knew Drew was getting married before she did!"
After nearly a year of dating, Will proposed to Drew over the festive holidays in Sun Valley, Idaho.
And the 37-year-old actress is rumoured to be pregnant after she was pictured with what looked like a baby scan, although her representative has refused to comment.
It will be Drew's third time down the aisle, following her previous marriages to Welsh bar owner Jeremy Thomas and comedian Tom Green.
