New York: Paris Hilton ignored her former boyfriend Doug Reinhardt, when she bumped into him while clubbing in a Hollywood pub, sources say.

The socialite, sporting a cleavage-popping dress, was partying with friends, including Brandon Davis, at new pub, My Studio.

"Paris and Doug were on opposite sides of the dance floor. It was a contest as to who was having the best time. He was with another blond girl and did his best to flaunt it. But Paris didn`t seem to care," the New York Post quoted a source as saying.

The hotel heiress left with her girlfriends late in the night, while stars including Adam Levine and Samantha Ronson continued partying.
