The Grammy-award winner went on a post-awards show drive with The Late Late Show host Monday, but the Biebs obviously missed the memo on what not to wear. Corden, wearing a white tux, noticed Bieber's exact same (yet dapper) look and was none too pleased.
"I thought it would be kind of cool," Bieber said when asked why he disobeyed Corden's request not to wear white.
"Oh, you thought it would be kind of cool if we looked like a pair of waiters on a cruise ship?" Corden responded.
But the British host mellowed out as soon as the "What Do You Mean?" singer helped him out by applying some moisturizer. "Just on the T-zone," Corden requested.
(Whatever keeps you oil free!)
Only when Corden was sufficiently moisturized could these two bust out into an awesome rendition of Bruno Mars' "Uptown Funk." The selection was a very appropriate one given that Mars took home the Record of the Year Grammy Award last night for his mega-hit song. The Into the Woods actor channeled the funk singer while Bieber played backup, which made for quite the dynamic duet.
They came together during the instrumental interlude where they both inserted their own lyrics and dance moves. "Big box, little box, cardboard box," they sang, mimicking squares with their hands.
The performers also rehashed the evening, praising Adele for her performance while also giving props to the evening's host, LL Cool J.
"He's a real, real stud," Bieber admitted, before giving Corden some compliments.
"I appreciate you. I appreciate the character you come with," Bieber gushed. "I appreciate your heart. You're such a kind individual. You love people."
Aw! However, it was only a matter of time before the cooing turned into a bitter spat. The two got to talking about the Grammy Awards gift bags, which tend to be filled with luxurious goodies. Unfortunately, not all goodie bags are created equal. Bieber pulled out a Rolex, a pair of headphones, a diamond bracelet, a mini iPad and a private plane trip to the Maldives, while Corden received slightly less ostentatious swag—Chapstick, a candle and a map of L.A.
"That actually put me in a bit of a mood," Corden admitted. "What does Justin Bieber need? Some more diamonds and an iPad?"
Touché, Corden. Touché.
