Rihanna is seen leaving the Mandarin hotel after taking part in a press conference for her new movie "Battleship" in London (March 28, 2012)

*Rihanna played the appalled card when a reporter at a London press conference for her movie “Battleship” tried to address rumors that she’s dating “Two and Half Men” star Ashton Kutcher.

Paps recently caught the singer leaving Kutcher’s Los Angeles home at 4 a.m., but she didn’t take kindly to one reporter asking whether he would be visiting her in the UK.

According to MTV News, Rihanna’s face “dropped” before she fired back, “Wow, how disappointing was that question. I’m happy and I’m single, if that’s what you’re really asking.”

Meanwhile, the Sun newspaper reports that Rihanna has been dating Ashton for eight weeks and even introduced him to her young brother Rorrey. The actor’s ex-wife Demi Moore – who recently completed a stint in rehab – is said to be devastated by the on-going speculation. A source told Closer magazine, “She’s really hurt by the rumors and feels humiliated he’s being linked to other celebrities just a few weeks after she got out of rehab. She feels it cheapens their marriage even further.”
