Prince Harry Off the Dating Market?

Has the most eligible prince in the world met his princess, of pop?

That's the rumor surrounding Prince Harry, England's most famous, young bachelor, now that he has returned to London after an Easter break in Transylvania and a Caribbean tour as a royal envoy for his grandmother, Queen Elizabeth.

The prince, 27, is said to be "smitten" with Mollie King, 24, a member of all-girl pop group The Saturdays.

The pair are "head over heels" with each other after first meeting two years ago at a polo game in which Harry played, according to the U.K.'s Daily Express. The two remained friends, the paper says, and romance blossomed after they reconnected at various London nightlife hotspots in the past few weeks.

British paparazzi spotted Harry, a bachelor known to enjoy a good time, singing karaoke with King and other friends at London's Bunga Bunga club last week.

"It's very early days for them but they're head over heels," a source told the Daily Express.

The tall and blonde King, who split from her Dolce & Gabbana model boyfriend two months ago, is described by British media as looking a lot like Harry's former girlfriend, Chelsy Davy.

Harry and Davy, 26, split last year after a nearly seven year on-again, off-again relationship.

Harry just moved into his own bachelor pad at Kensington Palace, the new home of his older brother, Prince William, and sister-in-law Kate Middleton.

While visiting the Caribbean and Brazil last month to mark the queen's Diamond Jubilee, Harry opened up about the difficulties of finding love as a prince.

"No, not at all," he said when asked in an interview with CBS News whether being a prince lives up to the fairytale.  "As any girl would ever tell you. It's sort of, 'Oh, my God, he's a prince'. But no.

"The job that it entails; I mean look at me, I'm 27-years-old, and not so much searching for someone to fulfill the role, but obviously, you know, finding someone that would be willing to take it on," he added.

Neither the palace nor representatives for King would comment on the rumored relationship.
