Lindsay Lohan Worried About Charlie Sheen

You know you're messed up when Lindsay Lohan says you party too much.

Charlie Sheen has hit a new Lo.

Sources close to Lindsay Lohan told TMZ the starlet is "worried" about Sheen because his most recent bender shows "obvious signs of addiction."

But LiLo - who has had several stints of rehab after a DUI conviction - says she's confident Sheen can get his life together if he commits to sobriety.

The source says Lindsay "understands the problem of having the wrong people around and wants Charlie to understand that he needs to surround himself with positive, sober people."

On Thursday, Sheen was rushed to Cedars-Sinai Medical Center after a boozy, drug-fueled party - complete with porn stars - inside his mansion.

He announced Friday that he'd be going to rehab again, putting his top-rated sitcom "Two and Half Men" on hiatus.
