Selena Gomez's dating rumors with different men is unending. After ending things with Justin Bieber in 2013, she has been constantly rumored to be dating several men. It is said that the latest news about her and her ex DJ Zedd is no different since they were spotted together again at the Z-100 Jingle Ball 2015. Is Selena sleeping around like her ex, Bieber?

Selena has recently denied reports that she's dating Niall Horan. Now Selena's dating rumors with Zedd is rounding up the Internet. According to Celeb Dirty Laundry, the "Good For You" singer performed with the Russian-German musician at the iHeartRadio Z100 Jingle Ball at Madison Square Garden in New York City on Friday, Dec. 11, and the two apparently did something backstage after their performance of "I Want You To Know." The gossip site reports that the former couple kissed and hooked up backstage.

The site went on to say that the two's passionate reunion was carried out on social media. "In the caption accompanying Gomez's Instagram post, the 'Good For You Singer' referred to Zedd as my babes. The Russian born DJ captioned his Instagram post, 'Reunion with my favorite lil Mexican taco to perform #IWantYouToKnow tonight at Madison Square Garden,'" the report said.

Earlier this year, Selena's dating rumors with Zedd came out after they were seen together in public. However, they never denied nor confirmed the status of their relationship.

After the "Same Old Love" songstress' recent sightings of making out with several men and denying relationships with them, it triggered more speculations if she's doing the same thing as her former Canadian singer boyfriend.

Meanwhile, a separate report from Hollywood Life contradicts the reports and says that Selena's dating rumors with Zedd is not true.

"Selena and Zedd have talked about their duet for a while," the insider said. "They have been at a few Jingle Balls together and they talk and hang out. There is no awkwardness whatsoever. He has told Selena that he is there for her no matter what because he knows she needs a friend more than anything right now as she transitions through moving on from Justin [Bieber] and seeing if she should continue with Niall [Horan]."

It was said that Zedd was just supportive and caring of Selena. Their relationship is over and he's just there for Selena as a friend.
