It's ON! Ben Affleck invited is Playboy model girlfriend Shauna Sexton for a sexy sleepover Tuesday night and he even escorted her out Wednesday morning at 7:45am!

No, Ben doesn't send his date home in an Uber ... he gives her a car! The 22-year-old model has been driving Ben's Ford Expedition for the entire time Affleck was in rehab and today was no different. He reversed the car out of his privacy drape-protected driveway and she quickly walked around the car, got in the driver's seat and pulled away.

Ben retreated behind the curtain with his dog and headed back inside.

Meanwhile, Ben's got two sober coaches with him so we're pretty sure there was no partying going on last night, just a quiet night at home for Ben and his devoted girlfriend. Who would have ever expected these two would last -- from their messy night out at Nobu a month and a half ago to her visits at his home with alcohol delivery, to now. Shauna stayed loyal to her man for the more than 30 days he was in rehab -- driving his car, running errands, doing her thing.


Yesterday, a very buff Ben dropped by Warner Bros. studios for another meeting yesterday afternoon, amid rumors he's eager to prove himself and reprise his role as Batman.

"He is back in shape not only for his health but he has a new-found love on doing Batman at least one more time again. He feels he isn’t finished with what he wants to do with the character. There has been talk about replacing him, but he is now seeing what he might lose and really wants to play the character again. Especially seeing what Joaquin Phoenix is doing with the Joker character,” a source dished to Hollywood Life.

“He would really like to take the character of Batman and visit a more serious tone and side of the character and working with someone like Joaquin would absolutely spark his creative juices. He wants to figure something out with Warner Brothers to don the cape one more time," the source added.

After that meeting, he headed to a recovery meeting with a sober coach and a male pal. Now that he's focused on sobriety, a career comeback would be the cherry on top!
