I am single: Rihanna

London: Rihanna has dismissed reports that she is dating `Two And A Half Men` star Ashton Kutcher.

The 24-year-old had sparked rumours of a romance with the star after she was outside of Kutcher`s house at 4am on March 22, the Daily Mail reported.

But she seemed upset when asked about her relationship status during the photocall for her movie Battleship here.

"I`m happy and I`m single, if that`s what you`re really asking," Rihanna said.

Kutcher is currently single following his split from Demi Moore amid claims that the actor cheated on his wife with another woman.
