Adam, whose hits include 'She Will Be Loved' and 'This Love', has previously dated 'Star Wars' actress Natalie Portman and model Kelly McGee - who the singer accused Robbie Williams of trying to steal.The handsome star was so furious when Robbie kept trying to woo sexy Kelly he had to issue the womanising star with a warning to stay away.Adam revealed at the time: "I'm having a massive feud with Robbie Williams.He kept hitting on my girlfriend. That man will hit on anyone. He's unbelievable. I had to warn the dude to stay away.

"She's hot so I'm not surprised, but he needs to steer clear. To be honest, he looked like he needed a hug from someone."

Adam is not the first pop star to date a tennis beauty - Spanish crooner Enrique Iglesias has been romancing Anna Kournikova for several years.
