We're shocked that he didn't buy a place with more privacy!

Ben Affleck took another break from rehab to go back to his Pacific Palisades mansion for a game of basketball this morning, and the actor had a curtain installed on his driveway to hide his comings and goings from the prying eyes of the paparazzi.

The Oscar winner was accompanied by his sober coach, and driven back to the Canyons rehab facility when his pick-up game was over. Normally, treatment centers don't allow you to leave the premises for the first 30 days no matter what, but they must be bending the rules to make him happy and keep him from quitting the program.

In addition to the support he's getting from ex Jen Garner, he's also got longtime BFF Matt Damon firmly in his corner.

"[Matt] continues to be a huge support. He’ll always be there for Ben whenever he needs him," a source dished to Us Weekly.
