Nick Jonas Gets Grilled On Dating Life by Demi Lovato, James Corden During 'Carpool Karaoke'

The morning commute just gets better and better for James Corden.

"The Late Late Show" had Nick Jonas and Demi Lovato to keep him company on the way to work for this week's "Carpool Karaoke."

The trio ran through a list of hits--from Jonas's "Close" to Lovato's "Stone Cold.

But the real treat was watching Lovato and Corden gang up on Jonas in the backseat about dating and that infamous purity ring.

"Are we going to keep talking about my dating life?" the 23-year-old singer said sheepishly.

Jonas got into better spirits when he karaoked "Chains," admitting he had totally been "tied up," as Corden put it.

"I was at a gay club, and they literally chained me to the wall as I'm performing the song," he said. "It's so hard being able to perform without using your hands."

Not if you're doing it right, Nick. Not if you're doing it right.

Lovato and Jonas will tour together starting in June. Longtime friends, Lovato joked at this year's GLAAD awards that she had "a bigger dick" than Jonas.
