Harry Styles’ One Direction bandmates are worried about his romance with Taylor Swift.

Niall Horan, Liam Payne, Louis Tomlinson and Zayn Malik think Harry, 18, is rushing into a relationship with Taylor, 22, too quickly and are also fearful she will write a damaging song about him if it ends badly.

A source told RadarOnline: “Harry’s public romancing of Taylor has got the other lads all riled up.

“With Taylor’s reputation for writing break-up songs about her exes, they think Harry could find himself in a spot of bother if it doesn’t work out and his actions are setting them all up for a fall.

“They also think it is moving too quickly and both have busy schedules, so it’s a difficult time for either one of them to commit.”

The ‘What Makes You Beautiful’ singers are also worried Harry’s relationship could affect their fan base as he is known as the heartthrob of the group.

The insider added: “Harry’s especially loved by the band's female fans and there is a feeling that by being so open about his relationship with Taylor he will only upset them.

“The boys are praying that when it does come down to it, he ends things amicably with her. Otherwise, they fear there will be hell to pay."
