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 spotted outside of Kutcher's house at 4am on March 22, according to a daily.

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.
