Is Rita Ora dating Tommy Hilfiger's son?

Rita Ora is reportedly dating rapper Ricky Hil, the son of American fashion designer Tommy Hilfiger, but her friends are concerned he may not be right for her.

The I Will Never Let You Down hitmaker - who recently split from Scottish DJ Calvin Harris - has been getting close to rapper Ricky Hil, the 24-year-old son of the prolific American fashion designer.

Ricky is said to be spending more time in London to be with Rita, 23, and the budding couple were spotted holding hands over dinner at Nobu on Saturday night.

A source told the Daily Mirror: "Ricky came over to Europe to hang with Rita a bit more this summer.

"They really hit it off when they met and really like each other, so Rita invited him over to join her.

"They want to see where things might take them - they're just having a lot of fun."

While Rita appears smitten with her new beau, it seems pals of the singer are less enthusiastic as they are wary of Ricky's bad boy past - including an arrest for cannabis possession in 2010.

The insider added: "He's a bit of a bad boy and a real world away from clean-cut Calvin. He openly boasts about smoking weed all the time on Twitter and has released mix-tapes called Support Your Local Drug Dealer. People are worried he might not be the best influence on Rita right now."
