HORNY Harry Styles invites up to a dozen girls a night to his hotel on One Direction’s wild UK tour.
His bonkers behaviour has stunned bandmates who “can’t keep up” with the 19-year-old.
Now Harry’s dad Des has had to step in and warn his son about his womanising ways.
Bandmate Niall Horan, also 19, told a pal: “Harry is just unbeatable. He never runs out of stamina! I’ve lost count of all the girls he’s pulled on this tour.
“He sleeps most of the day then does the gig and stays up all night with pretty girls in his room. He’s a total rock ’n’ roller.”
Another source close to the band told us: “It’s incredible, he seems to have at least three or four girls in his room every night.
“He’s totally out of control.
“Harry is totally brazen about it. He spots a girl he likes at a gig or when he’s out and about, goes right up to her and invites her to his hotel.
“He’s sex mad – it’s no wonder Taylor Swift couldn’t keep up with him and things ended badly.”
Harry stunned fans in Belfast last week by giving his number to a girl in the crowd and inviting her back to his hotel room.
Our insider added: “After nearly every gig on the tour so far he’s made sure there are loads of girls lined up at his hotel so he can take his pick.
“He’s had up to a dozen waiting on a single night. They all seem overjoyed to be invited back.
“The rest of the lads all hang out after gigs and watch movies or play their computer games. But Harry goes off with a harem of girls and you don’t see him until the next day.”
Despite his antics, Harry has been sending raunchy texts to Little Mix babe Jade Thirlwall. They got close when the pair auditioned for The X Factor in 2010.
Jade, 20, returned in 2011 and won the show but had a new fella by then.
Our source added: “Jade had a boyfriend when she saw Harry the following year so they tried to ignore the chemistry between them.”
