Every year celebs get knocked up, married and divorced, but a small handful always seem to end up in rehab.

This year Lindsay went to rehab (and jail!) twice for violating her probation, and Disney starlet Demi Lovato made her first trip to a treatment facility after a messy split from Joe Jonas and rumors of bullying.

Not to be one upped by the young ladies, Charlie Sheen went back to rehab after a scandalicious night with a porn star (not to mention a trashed hotel room and rumors of cocaine), and serial cheaters Tiger Woods and Jesse James checked in after their marriages crumbled.

So which celebrity rehab admission shocked you the most?
