Justin Bieber reportedly does not care about his former flames' love life. The Baby singer is apparently feeling grateful for getting a second chance with Selena Gomez, who he dated between 2011 and 2014.

According to HollywoodLife, as the 23-year-old singer does not want to mess up the reconnection he has managed to have the songstress, he is really "determined not to make the same mistakes that he's made in the past". So, Bieber couldn't care less about his former model girlfriend Yovanna Ventura, 21, spending time with The Weeknd, 27.

"Justin's got his eye on the prize, which of course, is Selena," a source told the celebrity gossip website. "He's reigning in any insecurities and keeping his jealousy in check."

Speaking about their relationship, the source said, "Justin is also allowing Selena to set the pace when it comes to their relationship, instead of strong-arming her as he's done previously."

The source added, "Justin thinks it's serendipitous that Selena's come back to him at the time he's decided to take a career break because it means he can totally focus on her and they can spend some real quality time together. Selena is the love of his life and Justin is determined not to let her slip through his fingers yet again."

Bieber and Gomez sparked dating rumours with their numerous outings shortly after the songstress called it quits with The Weeknd, who she dated for 10 months.

The Weeknd, whose real name is Abel Tesfaye, was recently spotted with Bieber's former flame Yovanna Ventura at hip-hop artist French Montana's birthday party, which was held at a Beverly Hills mansion in Los Angeles on Thursday, 9 November.

"The Weeknd was there hand-in-hand with Yovanna Ventura all night," a source told Us Weekly. "They arrived together. They were holding hands. He was there for a solid two hours with her and everywhere they went, they held hands."
