“Too busy” for love: 1D star Niall Horan dumps “devastated” model Amy Green

Niall puts his pop career before romance and tells friends he just didn't have enough time to be with Amy 

One Direction star Niall Horan has split from his girlfriend claiming he’s just too busy for love.

Friends say his career doesn’t leave him time for a serious romance, so he decided to end it with aspiring ­model and actress Amy Green, 20.

Drama student Amy, who herself ended a four-year relationship to be with the 1D idol, is said to have been left “devastated”.

A source close to the pair confirmed: “Sadly, it is over between Niall and Amy. He finished it because he didn’t have enough time with everything he has to do. Understandably she was disappointed because she had been in a relationship before she started seeing Niall and chose him over her boyfriend.

“But there are no real hard feelings and they’re still close.”

Amy, who is studying drama at the ­University of Birmingham, started dating the Irish heart-throb last October after they met at a London nightclub.

But pals say it was her who first threatened to end their relationship earlier this month. A source revealed: “She found Niall a bit too immature for her tastes.

“It was like Niall’s first relationship, whereas Amy had been in a relationship before. They had a few silly arguments and it was really the beginning of the end.” A source close to Amy, who now has well over 100,000 followers on Twitter because of the high-profile relationship, added: “Niall used all the tools he could to woo her and he treated her really well. She enjoyed it while it lasted and hopes they’ll stay friends.”

Last November ­Twitter trolls sent Amy abuse online. One wrote: “@Amy-Green92 You are dating Niall and now you think that you are famous? Attention seeker! Go away! Drama queen!” The tweeter added: “@AmyGreen92 I hope that Niall doesn’t see you without make-up because he will die!”

Niall, 19, who found fame on The X ­Factor with bandmates Harry Styles, 19, Louis Tomlinson, 21, Zayn Malik, 20, and Liam Payne, 19, told her to “ignore the haters”.

Worth an estimated £10million, Niall has in the past been linked to a string of beauties, including X Factor USA host Demi Lovato. But on Valentine’s Day he tweeted that he had only received a single card... from a little girl fan.”

Speaking outside her family’s North London home, Amy said: “I don’t know what I should or shouldn’t say. Sorry.” Niall said he’d “never felt happier”.
