Lindsay Lohan had an "embarrassing" angry rant on Tuesday night.

The 26-year-old actress reportedly had a public meltdown and was asked to leave Hollywood hotspot Bootsy Bellows when she refused to share the V.I.P. area with Clint Eastwood's daughter Francesca.

"Francesca was celebrating her birthday with around a dozen friends in a private area when Lindsay came over and started screaming that Francesca should leave. She was yelling, 'I'm a star, she's a nobody, get her out of here!' One poor guy came over and tried to calm [Lindsay] down and she acted aggressively. At that point the security told her to leave and it was totally embarrassing. She is acting like some bad 80s film star, and it is hard to watch because she needs help," one onlooker told Us Weekly.

The troubled starlet left the venue in a rage after her showdown with the E! reality star and almost caused a scene outside as she zoomed off in a friend's car. "Lindsay's friend was driving and they sped out and almost hit one of the valet guys," a party-goer said.
