Ungaro “creative consultant” Lindsay Lohan is slamming reports claiming she stole thousands of dollars worth of loaned designer accessories during her Paris Fashion Week debut earlier this month.

The actress allegedly borrowed jewels from jeweler Arielle de Pinto, but left the country without giving the diamonds back. The Mean Girls star has already been named in two missing jewelry scandals this year. For instance, in June, more than $50,000 worth of ice disappeared from a Lohan cover shoot. And just last August, Lindsay was left on the hook after some loaner pieces were left from her Hollywood Hills mansion during a break-in.

Nevertheless, Lindsay is emphatic that she had nothing to do with this latest case of missing jewels.

“That’s a lame lie,” the 23-year-old fumed in a posting on her Twitter page Monday. “Especially considering the people at the company are my friends and we laughed at this. F for failed attempt,” she added.
