How appropriate! She's been acting like that trainwreck Mushy Marissa Cooper for a while now!

Sources close to Lindsanity LOLhan are reporting that the hard-pAArtying wacktress will be doing her 90 day stint in rehab down in Newport Beach, CA.

She'll apparently have to check in to the facility, which specializes in alcohol and opiate detox, within 24 hours after leaving jail.

Excellent!

And sorry, bb! You don't get your time cut in half at rehab for overcrowding or good behavior!

Have fun!
