Pippa Middleton's beau better watch out because another British cutie has got his eyes set on her. One Direction's Harry Styles has allegedly got the hots for Royal Duchess' Kate Middleton's sister, Pippa. Rumour has it that Harry is dead set on dating the British brunette beauty.

Country crooner, Taylor Swift may be Hollywood pop royalty but Harry Styles may have called it quits from Swift because he'd been eyeing a different kind of royalty. The One Direction singer is reportedly eyeing the younger sister of Kate Middleton, Pippa Middleton, aged 29.

Despite having dated a lot of other women namely Kimberly Stewart and Taylor Swift, Harry Styles is apparently "bored of the showbiz set" that he's sought out the royals. According to reports, Styles has even come up with a list of royalties to date.

"Backstage before he gigs he was even trawling the internet, asking his band mates what they thought of each girl," stated an insider to the Daily Star, adding, "He drew up a 'hit list' and the only rule was they couldn't be married."

The Sunday newspaper reports that Kate Middleton's sister, Pippa Middleton is Harry's number two. Who made it to the number one spot on Harry's list then? Well, it would be none other than British princess, Eugenie. An insider reported that Harry is "totally fascinated" with the Princess claiming she's the "full package of class, looks and status."

Another princess Harry is eyeing is Princess Beatrice even having claimed she's not the "typical type of girl" Styles would go for. For now, Pippa Middleton remains the first royalty Harry would most likely try to seek out.

"He hasn't ruled out latching on to some of Pippa's party pals to try to help him manoeuvre his way in there," revealed the source, adding, "Harry really likes Pippa's friend Camilla Campion-Awwad, and is trying to get involved in her elite little circle."

With Harry's reputation and popularity with woman, it's unlikely a problem for the 1D cutie to find a way with these royal women.

"Harry has even secured a few phone numbers already through his high-flying contacts," continued the source.

The best of luck to Harry Styles then!
