Singer, model and reality TV bisexual beauty Tila Tequila has fueled speculation she's dating Drew Barrymore's ex Justin Long - by refusing to deny they hooked up at a Las Vegas party.

Gossips claim they spotted the odd couple together on two separate occasions in Sin City and then at a Los Angeles nightclub. And Tequila admits the rumors could be true because she can't remember the nights in question.

Tequila, who recently split from lesbian lover Courtenay Semel, says, "What happens in Vegas stays in Vegas, and it should just stay there... I don't remember anything."

Since splitting with ex-girlfriend Barrymore earlier this year, single Long has been linked with Kirsten Dunst.
