See More Pop Stars -- Then & Now

Demi Lovato and Nick Jonas are the latest celebs to take a spin in James Corden's "Carpool Karaoke" ride -- and this was a good one!

The late night host couldn't get through the trip without asking Jonas about his love life and his famous purity ring. And, of course, Demi got in on the fun too.

"You dated Joe (Jonas)," Corden started in on Lovato. "You dated Selena Gomez," he continued to Nick. "You two never.....?"

"Never!" they both replied.

After the songstress revealed that she's more into older men, she helped James get to the bottom of Nick's romantic life.

"It was Miley [Cyrus], then Selena, then back with Miley," explained Lovato. "Thank you Demi," Nick replied.

"It was Cyrus, Gomez, Cyrus, then Gomez then I don't know what else happened," the pop star continued.

"It was all during the time you're wearing your purity ring?" asked Corden. "When did you decide to ditch the ring?"

"I had a real relationship with an adult, and I fell in love actually, and I decided it was time to take the purity ring off," the former Jonas Brother explained. "Are we going to keep talking about my dating life?"

Nick got his wish, and the trio got back to the music. The group sang DNCE's "Cake By the Ocean," Jonas' "Close," Lovato's "Heart Attack" and more hits.

The musical gang then decided to pull up to the sidewalk and test out their new band, performing "Confident" with Corden on the drums, Jonas on the guitar and Lovato singing.
