The 24-year-old actress was wearing a yellow gold Cartier Love Bracelet on her right hand when she rolled into court earlier this morning, a bracelet priced at $4,850 on the Cartier website. She also had a giant diamond ring and other assorted bracelets on her left hand.

We're told the band was a gift to Lindsay from Samantha Ronson.

As TMZ reported, Lohan was also wearing pants and shoes from Lanvin, a body suit from Wolford and carried a purse from Fendi.
