Lindsay Lohan got her claws out in a confrontation with the Indian model wife of millionaire hotelier Vikram Chatwal, just days after the troubled starlet and Chatwal were spotted kissing at his home in New York.

Lohan rudely confronted stunning Priya Sachdev at the Dream Downtown on Wednesday night, saying with obvious disdain, “You are his wife?” This was followed by a sour face right out of her movie “Mean Girls,” spies said.

Dream owner Chatwal married Sachdev at a lavish seven-day ceremony in 2006, and they later separated. They have a daughter and have remained close. But Chatwal was seen kissing Lohan on photographs posted on the Internet as they cozied up near a window of his New York home a few days ago.

A source told us, “Lindsay had been staying at Vikram’s house and even installed her hairdresser in the baby’s room, but was told to leave before his wife arrived from India with the child a few days ago. His father, Sant Singh, has tried to order Lindsay out numerous times.

“Lindsay found out Vikram was hosting a dinner at the Dream, and turned up with a friend at the hotel’s Electric Room, waiting for him,” the source said. “That’s when the trouble started. Priya was very dignified, but Lindsay was so rude. She acted as if she’d had no idea Vikram was married, and tried to make it clear that Vikram was her friend. Others had to step in to calm things down.”

Chatwal flew Lohan to town before Fashion Week on his jet, and they’ve been repeatedly spotted partying together. Our source said, “Vikram’s family worry that Lindsay is bad news and want him to stay away from her.”

Lohan’s rep, Steve Honig, last night denied she and Chatwal were in a relationship. He said, “Vikram and Lindsay are good friends, and there is absolutely no romance going on between them.” Of the incident, “This is the first I’ve heard of it.” A spokesman for Chatwal said, “No comment at this time.”
