Ain't that sweet? Lindsay Lohan's fresh outta rehab and hamming it up with dear old dad! Months of detox didn't take the starlet's sense of humor. She describes her third stint in a year: "It was a sobering experience." Oh, zinger!

Lohan's exclusive (!) interview with OK does take a serious turn when she confesses: "I hit rock bottom. Everything in my life came to a point where I had to make a decision." Yeah, we go to rehab every time we have to make a decision, too.

Meanwhile, aforesaid father Michael's got a new lady friend. And, shocker, she looks like a future version of dear daughter Lindsay.

Frightful!
