According to sources, Justin wants Selena back and believes their split is just a temporary 'blip.'

A source told Mail Online over the weekend: 'It's not just over for Justin and Selena, whatever happens they have a lot to talk about.

'Their schedules have been packed but Selena has made tentative plans to see Justin in New York before his Brooklyn concert, she hasn't decided if she'll attend yet, but she's keen to talk... and so is he.

'They're both being a bit cagey and stubborn but they're desperate to see one another.

'This isn't new for them, they often have a tumultuous relationship. We all expect them to work it out.'

Further sources close to the Canadian singer have revealed that 18-year-old Justin is NOT involved with anyone else despite the fact that he stepped out with Hungarian fashion model Barbara Palvin, 19.

Palvin has also since taken to Twitter to deny any romance between her and Justin after receiving a deluge of messages from his devoted fans.

The 19-year-old begged the 'Belibers' to 'calm down' after they reacted to reports she was dating the newly single star following the break down of his relationship with Selena.

'Hey everyone. please calm down. he is all yours!! :) please :)' she wrote.

Sources also explained to TMZ that Justin felt that he and Selena have broken up before many times and that this split is just another 'blip.'

They added that the pop juggernaut is not 'freaked out' because he believes there's a good chance they'll get back together.

Last Saturday, Justin refused to confirm the split when he phone into a radio show.

He said: 'I don't know what to say,' he said in an interview with Open House Party.

'I don't know what's going on in my life. To even assess that it doesn't make sense 'cause I have not made any comment.'

Selena and Justin's split came after he was apparently seen 'chatting up' models backstage at the Victoria's Secret show last Wednesday.

The Canadian singer was then seen taking Palvin to see The Lion King on Broadway.

In a webchat 11 months ago she offered to sing her fans a song of their choice, but added: 'I don't like Selena Gomez by the way...'

But it seems she was trying to trying to take back the insult, as when fans tweeted her about the video, she told them: 'I do like her as an actress! she is talented!:) I did that ustream a year ago. Just forget it.:).'

However she was not shy to post images of her and the star at the high profile fashion show, and next to one where she is in her dressing gown with him, she said: 'Okay sooo because u guys were askin for it! with @justinbieber! you were great tonight!'
