The former couple have ignited rumours they may rekindle their romance after the 'What Do You Mean' hitmaker was spotted serenading the 23-year-old beauty at a bar on Friday (20.11.15) but an insider claims she isn't giving into him that easily.

A source told PEOPLE magazine: "Justin was in a great mood and serenaded her. She was still a bit pouty and playing hard to get.

"They were friendly at the [hotel] bar but they didn't act like a couple."

Meanwhile, the 21-year-old singer previously admitted the pair - who split in October last year - could get back together one day.

He said: "Maybe? We have a lot of history together and I am sure it could possibly happen. I think we are both just on our own journeys and figuring ourselves out and I think maybe once we figure ourselves out we can come back and make an awesome duo or she finds someone awesome and I'll find someone awesome. I just want her to be happy.

"She is someone I love dearly. I'm never going to stop loving her. I'm never going to stop checking in on her. I don't think if you end a relationship, you should end that, unless it was super toxic and you guys were hurting each other physically or mentally. We always respected each other and we still respect each other."
