Lindsay Lohan has plenty of family problems, but is she also in financial trouble? If these recent reports are to be believed, she's going off the deep end.

At least week's launch of Jermaine Dupri’s new watch line “NuPop” at Kitson, Linds apparently decided she wanted more than a nice watch to take home.

Although Linds was already being paid to show up, organizers offered the "actress" $500 to spend at Kitson, which she in turn bargained up to $1,000.

Lohan proceded to go crazy in the store, racking up a $15,000 bill.

Told she had exceeded her limit 15-fold, Lohan responded that she should be comped because “I’m the only celebrity here.” Guess she doesn't think that Jermaine Dupri himself, or Bridget Marquardt or Gretchen Rossi, qualify there.

Anyway, when organizers negged her, Lindsay "started talking smack about them to Jermaine Dupri who doesn’t even know her,” said an insider.

“He was totally bewildered and couldn’t believe it," the source added of Janet Jackson's ex. "Eventually they upped her limit to $2,000 to calm her down.”

A distraught Lohan then tried to bargain with the Kitson staff, insisting the boutique should let her take the remaining items for free. In exchange, she offered to “come in the next day and carry bags out so the paps could take shots.”

“The owner (Fraser Ross) couldn’t be reached so they told Lindsay to take the $2,000 worth and come in the next day and speak with him,” said a source.

Eventually the sulking starlet took her bags and stormed out in a huff declaring she would return for the rest. No clue if she actually did go back, though.

Later, she attempted to pawn an expensive bottle of champagne onto the credit card of none other than Kellan Lutz at Crown Bar. Never a smart move.

Do not anger the Cullens, b!tch.
