Many fans were really happy to see Selena Gomez and Justin Bieber back together, but to have a third party in the scene is not such a pretty sight. Just recently, the Canadian actor had dinner with a group of friends and he brought his girlfriend with him.

Apart from Justin's best friend Cody Simpson, another familiar face was also there and it's none other than Chantel Jeffries. Selena must have been really surprised to see her boyfriend's former fling in the same room. The manager of Cody Simpson, Justin Stirling, posted the group photo on Instagram. He captioned it, "nobu dinner with da crew" and you can see Justin and Selena at the back while Chantel sits in front near Cody.

This isn't the first time that the 20-year old pop star was seen with his former flings after reports came out that Selena Gomez and Justin Bieber have reunited. A source told Hollywood Life, "Justin flew out Yvonna (Ventura) to Fashion Week on his dime on Sept. 9 and then went to Vegas to be with Selena. So he is having his cake and eating it to."

I guess the Biebs will never change because he has a reputation of flirting with many girls even while in a relationship with Sel. Maybe the 22-year old actress has learned to trust him more and not let jealousy ruin their relationship.

Hollywood Life reported, "It looks like Justin is not quite ready to give up hanging out Chantel, but hopefully they're just friends now that the Biebs has rekindled his love with Selena. We highly doubt Justin would be parading Chantel around in front of Selena if he was still romantically interested in the model."

The website also said, "This must have been a very awkward night for everyone involved - especially poor Selena!" We really feel for her so hopefully there will never be encounters between the singing heartthrob and his former flings. Do you think Selena Gomez and Justin Bieber's relationship will last for a long time?
