Lindsay Lohan Returns Borrowed $1,750 Designer Dress in Tatters: PICTURES

Shear madness? Lindsay Lohan wore a gorgeous, beaded, floor-sweeping gown by Theia to an amFAR event on Feb. 6 in NYC, but by the time she returned it, the dress was half its original length.

"She said that the dress had ripped [at a club after the fundraiser] -- she couldn't possibly wear it like that -- so her stylist friend went to the club bouncer and requested some scissors to repair the torn part of the dress," a source tells Us Weekly. "But what bouncer has scissors?"

"She turned it into a mullet! Only a fashiony person would do that! " the source continues. "She's out of control and behaving really badly."

The dress in question is actually the same one that fellow troubled star Charlie Sheen finagled for the 26-year-old actress. As revealed by Us Weekly, Sheen generously hooked up his Scary Movie 5 costar with the dress after personally putting in a call to celebrity stylist Phillip Bloch to outfit her for the glamorous AmFAR affair.

He even said he'd "go halfsies" with the actress to pay for the gown, an offer she did not accept: Lohan ended up borrowing the dress.

Last year, the actor offered to lend Lohan $100,000 to help cover her tax debt. The actress was said to have refused the money.
