Diaz & Barrymore's 'Joint' Vacation

Both having recently broken up with their boyfriends, Cameron Diaz and Drew Barrymore decided to spend a joint holiday together... with the word 'joint' having more than one meaning.

Drew Barrymore and a boatload of her friends, including Cameron, invaded the beaches of Kauai to celebrate her 32nd birthday.

The close pals and Charlie's Angels co-stars were spotted sharing a rolled up joint on the Hawaiian island, with pictures by Splash News Agency supporting the claim.

"Drew passed the ciggie to Cameron, 34, who checked the coast was clear before taking a long drag," reports the News of the World.

"Cameron's eyes were half shut and she leaned back so far she was almost horizontal," a source reported.

The two have seemingly become much closer pals after Cameron split from Justin Timberlake and Drew broke off her relationship with Strokes drummer Fabrizio Moretti.
