James Corden has clearly spotted a winner. The Late Late Show's Carpool Karaoke has attracted nearly 300 million views on YouTube from music fans desperate to see the likes of Adele, Elton John, Stevie Wonder, One Direction and Mariah Carey belt out their hits while squeezed in next to the British comedian.

Carpool Karaoke veteran Justin Bieber completed his hat-trick of appearances on Monday night when he joined Corden on his journey from the Grammy Awards back to the set of The Late Late Show. For this appearance Bieber made sure he was dressed in an identical white tie outfit to Corden, causing the latter to feel slightly unsettled: "I'm freaking out," the agitated 37-year-old shouted. He later went on to suggest that the duo looked like "a couple of waiters on a cruise ship."

Bieber decided to celebrate his first victory at the Grammy Awards in a generous fashion, opting to sing-a-long not to his own track, "Where Are Ü Now" which won Best Dance Recording, but to the winner of the highly prized Record of the Year Award—Mark Ronson and Bruno Mars' "Uptown Funk".
