New York: Jennifer Lopez and DJ megastar Tiesto may be working on a new song together.

The `On the Floor` singer was overheard asking for the DJ as she and beau Casper Smart partied at the opening of the 80,000-square- foot Asian restaurant Hakkasan in the MGM Grand Hotel and Casino in Las Vegas, the New York Post reported.

The Dutch musician was later seen talking to the mum-of-two about "possible collaborations," according to the paper.

Vanessa Hudgens, Pharrell Williams and Paris Hilton also attended the lavish bash.
