But are David and Jennifer supportive of Selena's romantic reunion with the Biebs? According to Radar Online, some of the "Come and Get It" singer's friends are none to happy about the rekindled relationship.

"Selena's friends have stuck by her through thick and thin," a source explained. "But the whole back-and-forth relationship with Bieber is really starting to wear on then. None of her friends really like Justin, or at least, they don't like Selena with Justin. It's just not a healthy relationship. He has something on her. She knows he's not the right thing for her, but she can't stay away. Her friends have given up and the last thing they want to do is be around for another Jelena breakup."

Gomez, who turns 21 on July 22, and Bieber split back in late 2012 after dating for around two years. This has been an on-and-off again 2013 for the two pop stars, so far. Rumors surrounding the two reuniting have come up pretty much every month.
