Are Kendall Jenner and Justin Bieber dating?

Gossip columns claim that the long-time pals have already taken their relationship to another level. The rumors sparked when the pop sensation posted a photo of him and Kim Kardashian's younger sister cozily petting his puppy in their swimming attires. The two were also constantly photographed together, particularly during Coachella.

The two were also seen being cozy with each other during a Vogue magazine photo shoot, as well as during Bieber's Comedy Central Roast, where the 21-year-old daughter of Kris and Bruce Jenner was seen sitting in the front row.

But sources close to the celebrities denied the rumors, saying that the two were absolutely not dating.

The source told Radar Online that The Biebs and the fashion model are not exclusively seeing each other, and they are just hanging out as friends.

"The two of them have been super close for years but Kendall took a step back from the friendship when Justin was partying and acting up," the source said. "Kendall is not about to be a rebound to Selena Gomez, nor does she want the drama of a lying and cheating boyfriend."

Several entertainment websites also offered their unsolicited advice to Kendall if she decides to really date the 21-year-old worldwide pop heartthrob. A source divulged to HollywoodLife that it would be hard to ask Bieber to commit to a single woman right now.

"Justin knows he's not ready to be with one girl. If he was, he'd be with Selena [Gomez]," the source mentioned. "Right now, he wants to have fun and enjoy his life. He doesn't make promises to anyone!"

Bieber's longest relationship was with singer-actress Selena Gomez. The two were and on-again off-again couple for the last four years. It would not be impossible to expect that the two can still get back again together anytime soon.
