Niall Horan has reportedly moved on from his Selena Gomez fling with Irish model Thalia Heffernan. He met her in May when he was visiting Ireland, and they are determined to make things work. Congrats to the new happy couple!

"Niall's never in one place for long and Thalia travels the world modelling so it will be a case of whenever they can manage it," an insider revealed to The Sun.

Horan is currently on the "Where We Are" tour with his band One Direction, while Heffernan is doing modeling work in Australia the next few months.

This comes on the heels of reports that Gomez is back on again with Justin Bieber. The troubled star posted a picture with Gomez to his Instagram account. The on/off lovebirds were cuddled in an adorable black and white snap, which has since been deleted, captioned, "our love is unconditional."

Jelena spent time in Canada together for Bieber's dad Jeremy's birthday. A family friend spilled the beans on her twitter account that Gomez joined in on the family trip.

She tried to redeem herself with, "Oops wrong name in my last tweet.....what it meant to say....."

"Had an amazing b day weekend thank you @ErinWagner @JeremyBieber @justinbieber @pattiemallette @CrazyKhalil had a blast!!"

Horan took Gomez to a Katy Perry show in May, further fueling rumors they were a couple.

"Niall and Selena have always got on well and communicate regularly," a source told the newspaper. "It will always be tough having a serious relationship given their schedules, so they're just having fun."
