Where was our invite?!

Bradley Cooper and Irina Shayk are on vacation with some of their famous pals, and it seems they hired a babysitter for newborn daughter Lea Siene to enjoy a little downtime in Tahiti. The pair were joined by Anderson Cooper and his boyfriend Benjamin Maisani, Andy Cohen, Allison Williams and her husband Ricky Van Veen, and Diane Von Furstenberg.

We're slightly surprised that Brad Pitt didn't tag along for the fun. According to a new report, the Silver Linings Playbook star has been a support system for BP as he gets sober. Bradley ditched the booze years ago, and has been giving the father-of-six advice on how to stay alcohol-free.

"Bradley’s been sober for years and is so happy for Brad, who he only knew loosely until recently. He’s been giving tips about good meetings to go to and little tricks he uses whenever he’s feeling tempted or surrounded by bad influences," a source dished to Radar.

"Brad’s been educating Bradley about art [recall he’s also been hanging out with Leo DiCaprio at his sculpting studio] and they’re looking forward to hanging out together with Irina and other pals back in LA. This isn’t about hooking Brad up with a new girlfriend, but keeping him grounded and providing him with a sober support system," the source added.

What a great group!
