Paris Hilton will reportedly have a Vegas birthday bash in March. The hotel heiress is also said to be inviting ex-boyfriend Benji Madden to her private party.

Hilton, who was born on February 17, 1981, will allegedly celebrate at the Hard Rock Hotel and Casino in Las Vegas on March 6 to 8. She will be hosting her own party at Body English on Saturday night. Two private parties had been booked in the penthouse for her and 30 of her closest friends' enjoyment.

Paris Hilton snared Robert Pattinson at a party.

The blonde hotel heiress stunned guests at a lavish Oscars bash by dragging the "Twilight" star outside for some time alone after asking her younger sister Nicky to help track him down.

Paris Hilton is reportedly desperate to win back ex-lover Benji Madden. The hotel heiress - who split from the Good Charlotte rocker last November - has been consumed by jealousy after seeing pictures of Benji spending Valentine's Day with U.S. singer Katy Perry.

A source said "Paris still has very strong feelings for Benji and seeing those pictures has really hurt her - especially as they were taken so close to her birthday. She is determined to get Benji back and she is not going to let anyone or anything stand in her way."

Katy Perry has denied "bumping uglies" with Benji Madden. The "Hot n Cold" singer sparked rumors she was dating the Good Charlotte rocker when they were spotted enjoying a cozy evening in Las Vegas on Valentine's Day, but she insists they are just friends.

She wrote on her blog: "It's two pseudo famous people sitting next to each other... doesn't mean we were bumping uglies! You know I don't just do that with anyone!"

Paris Hilton has a crush on Robert Pattinson. The blonde heiress fell for the handsome British actor when she watched his latest film, in which he plays a vampire.

She said: "I just saw 'Twilight' last night for the first time, and I have to say that I think Robert is a beautiful man and an amazing actor. He's fabulous!"
