Justin Bieber and Selena Gomez Split!

Justin Bieber and Selena Gomez have split up according to reports from the US.

It is claimed the teenage love birds called time on their relationship over a week ago.

A source said: “Because of their crazy schedules, it was getting harder and harder to maintain a relationship.”

That may be the official(ish) line, but other reports this week have suggested Justin is developing a keen interest in a certain underwear model.

Speculation is rife that Bieber has become more than just friends with Victoria’s Secret model Barbara Palvin.

They were spotted together at a show on Broadway just a few days ago and the night before, Hungarian Palvin, also 18, tweeted a picture of them (above) at a fashion show.

Palvin has denied being any more than friends with Bieber, tweeting on Friday: “hey everyone. please calm down. he is all yours!! :) please :)

The Bieber and Gomez split comes almost two years after the couple first went public with their relationship at the Vanity Fair Oscars party in 2011.
