According to Star magazine Brad Pitt is obsessed with his looks.

When family members tease Brad about Restylane injections to erase wrinkles, he gets defensive.

"He says, 'It's my job to look good.'"

Another insider also revealed "he still smokes."

"He sneaks cigs behind Angie's back."

At the Cannes Film Festival in May, "He stayed outside, smoking, and drinking. He looked stressed, like he was trying to get his fill because he had a limited time to enjoy his cigarettes."

A source tells Star he spotted Brad smoking what looked like a joint with Jackass madman Steve-O.

"But there he was, lighting up a fattie with Steve-O. I was stunned."
