Justin Bieber talks underwear, starting a family and sings his hit songs in ‘Carpool Karaoke’ with James Corden

Justin Bieber rode shotgun with James Corden and it was filled with singing, dancing and some interesting confessions.

According to E Online, the 21-year-old singer and the Late Late Show host drove around L.A. as part of Corden’s popular segment “Carpool Karaoke.”

To start their fun-filled ride, Corden played Bieber’s hit song “Baby." The two danced and sang along to the catchy tune and Corden impressively rapped Ludacris' entire verse.

Corden managed to work in Bieber’s Calvin Klein campaign into the conversation. He jokingly admitted to not knowing who Bieber was since he “had a top on.” He then went on to ask if the brand sends Bieber free underwear for life.

“They send me a lot of Calvin Klein, like, boxes and boxes,” Bieber replied.

“Do you just wear them once and then throw them out?” asked Corden.

“Yeah, yeah. I definitely don’t wear them twice," Bieber admitted. “There’s just so many.”

He then went on to play Bieber’s 2012 song “Boyfriend” and even gave the singer some critiques on his lyrics, in particular, the lyric “chillin’ by the fire while we eatin’ fondue.”

"That's the line where I'm out because fondue is not a good date food,” he told Bieber. “You'll end up with cheese dripping down your face."

After eating some fries, watching in awe as Bieber successfully completed a Rubik’s cube and having a dance party to Bieber’s song “Where Are Ü Now,” Corden asked, “Where does Justin Bieber want to be in ten years time?”

“I want to be completely secure in myself and have a family,” Bieber answered.

The two concluded their joy ride in style and jammed to Boyz II Men’s classic song “End of the Road.”
