Orlando Bloom dirty danced with Madonna at an Oscars after-party.

The 31-year-old actor reportedly stunned onlookers by enjoying a "steamy dance" with Madonna before kissing two stars at a Hollywood Hills bash on February 24.

A source is quoted as saying: "Orlando was loving the attention when he was dancing with Madonna. He was really going for it."

Orlando, who is dating Victoria's Secret model Miranda Kerr, was later seen canoodling with 19-year-old Rumer Willis - the eldest daughter of Bruce Willis and Demi Moore - and British photographer Amanda De Cadenet.

The source added: "Orlando couldn't keep his hands to himself when he was dancing with Rumer. He was touching and kissing her. Soon after he did the same thing with Amanda. It was hilarious."

"P. Diddy, who was the MC for the night, called out, 'Orlando - how many girls you going to kiss tonight?!'"
