Hilton dedicates song to new boyfriend

Paris Hilton has dedicated a performance of her 'Stars Are Blind' single to her new boyfriend Doug Reinhardt.

The heiress took to the stage and sung her hit at a belated birthday party in Las Vegas, The Sun reports.

Baseball player and former Hills star Reinhardt had previously toasted his partner as "the world's prettiest girl".

Hilton said: "My man is right over there, the sexiest man in the world."

She reportedly added to friends: "Tonight will be more low key so that for tomorrow we will do it up, and who knows someone might get arrested. But we are in Vegas, so let's party!"

Hilton had invited her fans to join the first leg of her birthday celebrations in a MySpace post last week.
