Simon Cowell "Impressed" About Harry Styles' Romance With US Star Taylor Swift
The 'Little Things' star's label boss says he doesn't worry about the band's activities outside of music.
Simon Cowell has admitted he was "impressed" when he heard about One Direction star Harry Styles and Taylor Swift's romance last year.
The X Factor USA judge also says he would never interfere in the boy band stars' lives unless they really went "nuts", and doesn't' believe having a "couple of tattoos" is an issue.
"I don't believe in the horrible idea of me or the manager telling the guys what they can and can't do," Simon revealed to the Daily Star this week. "If they really go nuts then I would step in but having a couple of tattoos and a couple of girlfriends isn't a problem."
The Syco boss went on to comment on Harry's short-lived romance with US star Taylor Swift, which ended at the start of January after a holiday to the Caribbean.
"Harry doesn't hang around, so yeah, I was impressed about Taylor," the music mogul admitted. "I don't worry about the One Direction lads because I speak to them a lot.
"If there are ever any issues then we deal with them quietly as friends," Simon added. "I told them to treat this as the best time of their lives and don't treat it as work."
