Chris Brown has warned Justin Bieber that he might end up losing Selena Gomez forever if he does not stop his "womanizing" ways and continues to flirt with his ex-flame. The advise comes from the experienced Kiss Kiss singer who split from two of his partners: Rihanna and Karrueche Tran.

"Chris is sitting back, looking at Justin's antics and shaking his head. For starters, Justin is acting like a younger Chris. Arrogant, womanizing, breaking hearts and acting like his sh** don't stink. Chris wants JB to know that ain't cool and that he'd better stop juggling these girls like he's at a circus before he loses the love of his life," a source told HollywoodLife.

"Chris had to learn the hard way and he only wishes he never played Rihanna or Karrueche like he did. It's obvious to Chris that Biebs and Selena belong together, and he only hopes JB realizes that before she walks out of his life forever," the insider added.

It seems like Bieber is finding it difficult to let go of Gomez, after the 22-year-old shared a photo of on Instagram on 19 March, of himself and his former girlfriend kissing. Nonetheless, Gomez "liked" the photo and called it "perfect". The two dated from 2010 until 2014 before parting ways.

It was previously reported that Bieber was not happy seeing Gomez with another man. "Justin feels awful that Selena thinks relationships are hard after they dated. He never, ever wanted to hurt her or make her have a bad taste in her mouth about future relationships because of their own ups and downs," a source told the gossip site.

"On one hand, the thought of seeing Selena in a serious relationship with someone else would definitely be hard to swallow. But on the other hand, he wants her to be happy. He hopes she can forgive him for past hurts and not let all that old drama stifle her love life or more importantly her self esteem," the insider added.
