Demi Lovato just celebrated her cover on Nylon Magazine at a big party, where she may have awkwardly run into her ex, Joe Jonas. The "Let It Go" singer and "X Factor" judge may have come face-to-face with him, prompting more rumors that she may still love the JoeBro.

But could the former Disney darling really have feelings for Jonas after their break up and his recent confession of doing drugs with her several years ago?

According to Hollywood Life, the crooner was scheduled to attend a party for the blue-haired starlet, who may have been uncomfortable about it, on Thursday.

But given that the starlet is surrounded by rumors that she may be pining after the crooner again, some say that Lovato wouldn't have minded running into Jonas.

Recently, the two had been talked about when Jonas opened up about his past with his former girlfriend. 

The JoeBro had also recently broke his silence on his high-profile break up with his brothers, Kevin and Nick in New York Magazine. But the singer didn't mind dishing about his past, including smoking weed for the first time with Miley Cyrus and his ex, Lovato.

"I must have been 17 or 18," said Jonas, who chalked up the experience to peer pressure. "They kept saying, 'Try it! Try it!' so I gave it a shot, and it was all right. I don't even smoke weed that often anymore..."
