Lindsay's Learned!

That's right people, there you have it. What is the recently-released-from-rehab starlet doing today, on her birthday? Partying? Boozing? Nope... jogging! Ms. Lindsay Lohan was spotted going on a run with her friend in a hot pink bikini top. It's super warm on that Malibu beach, but it doesn't seem to be bothering Linds - she's a real trooper! These are the kind of pics we want to see. And she certainly, uh, fills out that top.
