Ahh the perks of dating an A-lister!

Ben Affleck's Playboy model hookup Shauna Sexton went shopping yesterday afternoon after their sleepover, and she was driving the Oscar winner's black SUV! Normally we see her in a bright blue beat up Acura, so the actor must have felt sorry for her and lent her a fancier whip.

The Batman star's ex Jen Garner isn't too thrilled he seems to be more focused on his new romance than his sobriety, but she's trying not to get too involved and simply leave it up to the team of professionals in charge of his recovery.

"He had stayed in touch with Shauna the entire time he was in rehab and the people at the facility and friends had huge concerns about it because she isn't sober. She is a huge, red flag to everyone that is trying to support Ben with his process. Shauna is giving him false confidence and that is their biggest concern," a source told ET.

"Jen knows he is back at the house with Shauna and she is so painfully frustrated. She knows he has to do this for himself," the source added.

Radar reports that the pinup has decided to be sober, in hopes of maintaining her relationship with the Hollywood hunk. Does she really think she's more than a booty call? Poor girl!
