Orlando Bloom is reportedly romancing Rumer Willis.

The 31-year-old actor was seen canoodling with 19-year-old Rumer - the eldest daughter of Bruce Willis and Demi Moore - at Prince's 'purple' Oscars party on Sunday.

A source said: "The chemistry between them was electric. They were all over each other and didn't seem to care who saw them."

Last week, Victoria's Secret model Miranda Kerr, who is rumored to be dating the handsome 'Pirates of the Caribbean' star, said Orlando was a "sweetheart".

She coyly told People magazine: "He's a sweetheart and that's all I'm going say. A real sweetheart."

Earlier this month, Orlando and Miranda were seen kissing at New York's Max Brenner Chocolate café where they bought two mocha hot chocolates.

A source said: "They made out the entire time they were waiting in the line. They only had eyes for each other."

Orlando previously dated actress Kate Boswoth for four years.
