Selena Gomez And Justin Bieber: Jealously Leads To New Lovers? On-Off Couple Splits, ‘Heartbreaker’ Star Spotted With Ex-Girlfriend

Selena Gomez is rumored to be dating Union K band member George Shelley and Justin Bieber was spotted with his ex-girlfriend Jaque Ray Pyles at Las Vegas, leaving fans wondering if jealously led to the couple slitting and making new loves.

Justin Bieber was spotted with his old flame on a private jet, just days after the former couple was spotted front row at New York Fashion Week. No word on whether she's officially made him her boyfriend, ExtraTV.com reports.

But some have speculated that Justin Bieber and Miley Cyrus, who recently broke up with Liam Hemsworth, would make a good couple.

"You're 20, he's 19. You have the #1 hit on the music charts, and on VEVO views, with 'Wrecking Ball," and he's the #1 male pop star. Who could understand you and what you're going through more than Justin?" writes HollywoodLife.com. 

"And it's not just that you two both know what it's like to be a teen music star, and then successfully transition to an adult pop star - you have now both been through painful break ups."

Selena, 21, and George, 20, reportedly took the next step in their relationship when she flew his whole band to Portugal to open for her concert in Lisbon on Sept. 11, HollywoodLife.com reports.

Selena Gomez reportedly hosted an after party in her hotel room, and George stayed later than everyone else: "She invited all the Union J boys and some other members of her entourage to her room and they had a great time drinking and dancing. Selena and George were all over each other and things got very heated," HollywoodLife.com also reports.
