Justin Bieber has a few weeks more before the year ends to get Selena Gomez back and the singer is confident about it, The Hamilton Spectator reported.

Justin Bieber is reportedly on his way to pursue Selena Gomez again. Bieber is allegedly bragging that getting his ex girlfriend's affection is a piece of cake.

"Justin bragged that he's got so many girls, and could get any girl he wanted, including Selena," the insider revealed.

Bieber's hair transformation and Instagram posts were reportedly a way to pursue his former flame.

"Justin hopes Selena saw the photos. He wants her to see how good he looks. How healthy he is and that's he's changing for the better. He hopes the pics impress her," a source said, according to Hollywood Life.

Gomez has allegedly given her former beau until New Year's Eve to make up with his past mistakes.  A source said that the "Come and Get it" singer is exhausted from the on-and-off relationship.

"If Justin doesn't make a move to win Selena back before the new year, she will move on from him 100%. She's patient - patient like a saint - but she's tired of his immature behavior. She wants to eventually settle down and have a family one day. She's not going to wait around for Justin to grow up," the source said.

The couple has an unstable relationship since 2010. Gomez reportedly wants a serious commitment from the pop prince, who was linked with several women on the course of their romance.

"If Justin whisked Selena away on a romantic holiday vacation and gave her a promise ring, that would do the job. Selena is not a high-maintenance prima donna, but she does want her man to treat her like his queen,"  the insider added.

In a recent interview with NRJ radio in Norway, the brunette beauty confirmed her never ending affection for her former beau.

 "I definitely have so much respect and love for him," Gomez said, according to Gossip Cop.

As the saga continues, who knows what will happen to the pair before the year ends.

Meanwhile, Gomez just signed a recording contract with Interscope while Bieber is rumored to release an album in 2015.
