This doesn't sound good.

We caught Ben Affleck dropping by his Pacific Palisades mansion this morning for another workout, and we're hoping the latest reports about his struggles in rehab aren't true.

Apparently, the Oscar winner isn't taking to treatment too well, and is being a little too casual about his recovery.

"He hasn't been cooperative at all. He went to rehab to detox and does not seem to have any intention of staying sober," a source dished to Radar.

We have thought it was weird that they keep allowing the actor out of the facility on a daily basis to dictate his own routine. Usually, part of the process is abiding by the rules for at least the first 30 days, and patients aren't typically allowed to return home and hang out with their Playboy model girlfriends in between group therapy sessions.

Speaking of, we caught Shauna Sexton leaving the gym in his black SUV this afternoon, and we asked for an update on her romance with the Hollywood hunk... watch!
