Cameron Diaz searched for her keys at the bottom of her Reed Krakoff bag yesterday after visiting a friend's house in LA. She showed off her California-girl style, pairing short denim cutoffs with a bright yellow bag. Cameron's on the West Coast at the same time as some of her best friends. Drew Barrymore was treated to a baby shower organized by Cameron last week. Cameron's other close friend, Gwyneth Paltrow, has also been seen out and about in Hollywood recently. Gwyneth, whose book My Father's Daughter came out in 2011, could offer Cameron some advice on a new project. Cameron's working on a health and wellness book for women, scheduled to come out some time next year.
