If Nialler is your favorite member of One Direction, you're in luck! Niall Horan has reportedly split with girlfriend Amy Green. Demi Lovato, are you paying attention?

Sources told The Mirror that Horan's hectic schedule simply got in the way of his romance with the aspiring model and actress. The pair were first linked in October 2012, but they each spent Valentine's Day solo.

“Sadly, it is over between Niall and Amy," a pal said. "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."

Though Green was bummed about the breakup, it turns out she almost dumped poor Horan previously.

“She found Niall a bit too immature for her tastes," the source admitted. “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.”

Still, one of Green's friends revealed, “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.”
