Lindsay Lohan and Jessica Simpson have recently begun a new Hollywood feud after the two starlets had a falling out in a nightclub in Los Angeles.

It all began last week at after Lohan sent a round of drinks to Simpson, who, it seems, didn't say thank you. It has been said that Lohan confronted Simpson and even made her cry.

Lohan's possible new boyfriend, director Brett Ratner, who incidentally directed Simpson's "These Boots (Are Made For Walkin') video, supposedly stepped in to break it up.Lohan did eventually let it go, returning to her own table, while Simpson left the club shortly after the confrontation.

Speaking of Lohan and Ratner, rumors of their possible romance started flying after they were spotted at a party at the very same club where the fracas took place.

Ratner, 37, who is almost twice Lohan's age, has been most recently linked to tennis star Serena Williams. Lohan's past romances have included Wilmer Valderrama and Jared Leto.
