Lohan Enters Rehab

TMZ has confirmed that Lindsay Lohan has checked herself into rehab.

In a statement issued through her rep, Leslie Sloane Zelnik, Lindsay says "I have made a proactive decision to take care of my personal health. I appreciate your well wishes and ask that you please respect my privacy at this time."

Lindsay's mom, Dina, revealed last month that Lindsay had been attending AA meetings.

It's been a tumultuous few weeks for the "Mean Girls" star. Just two weeks ago, 20-year-old Lindsay underwent an operation to remove her appendix.
