Saif Ali Khan stirred up trouble in New York city by reportedly squabbling with his co-star Rani Mukherjee and also vexing the owner of Madame X lounge.

Saif who is in the Big Apple for the shooting of his film Tara Rum Pum apparently threw his weight around at the posh bar after downing shots of Tequila.

Buzz is also around that Khan and Murkerjee, have reportedly asked their producer for rooms at separate hotels so they don't have to see each other off the set.

The other night, the hunky millionaire and some pals stopped in at Madame X on Houston Street. A bartender there said Khan copped an attitude while throwing back shots of tequila and downing rum and Cokes.

"He acted like he owns this joint," the owner was quoted by the New York Post, as saying.
