James Corden and Adam Levine Get Pulled Over by Police During 'Carpool Karaoke'

After the late-night host and the frontman of Maroon 5 took a break to balance objects on their face, they got back on the road and started singing the band's 2002 hit "She Will Be Loved," which was interrupted by sirens. "What do the police want?" Corden asked his guest, then rolled down the window to ask the officer what was the matter.

"I want to pull you over so he can sing a song for me," the cop said. "Because you can cause a traffic hazard."

Both Corden and Levine got a kick out of it, with the CBS star telling his guest "this is a real first," then asking, "How are you being so cool about this?"

Our guess? Adam Levine is cool about everything.

Then the dudes got real about something bigger than music: parenting.

"And so I'm now raising fully fledged Angelino children, but my worry with kids growing up here -- my new daughter her first words are going to be, 'Oh my God, dad. This is crazy,'" Corden said in his best valley girl accent. "How are you going to stop your daughters from sounding like this?"

Levine's strategy: "I'll be like, 'You sound like a f-cking moron, don't do that.'"

The boys wrapped up a very fun morning drive with a racing challenge on a private race track.

"You have to drive as fast as you can around the course whilst answering general knowledge questions," Corden said. "For every question you get wrong, we will add a second to your time."
