One of James Corden’s dream carpool karaoke passengers, Bruno Mars, helped him get to work yesterday. (The others are Beyoncé and Kanye West.)

They sang ‘Grenade’, ‘Uptown Funk’, ‘24K Magic’ and(sort of*)confirmed the new album titlefor Bruno’s next album, 'Wine and Wet Wipes.'

In the new segment, Corden subjected Mars to some tough questioning. “I want to talk through the hats,” said Corden. “I feel there isn’t a hat that you can’t wear.”

“You know where the hats come from?” replied Bruno, threading his hand through his curly mane, “it’s because of this hair. I don’t know what do with it.”

Now you know.

Carpool Karaoke has become so popular that nobody, anywhere, is even sure if James Corden still presents a late night talk show or not. (If you know if he’s still hosting that thing, please write in to MTV Towers.)

“I’d catch a grenade for you,” said James, “if the pin was in. But if you’d taken the pin out, I’d run.” A pause. The pair stared at one another. The pause continued.

“That’s f*cked up,” said Bruno.

Meanwhile, Bruno Mars will soon be jetting off on a mammoth world tour. Spanning across 100 dates, the tour will see Bruno out on the road for most of 2017. Want tickets? You can’t have any.Bruno Mars is so popular that he sold out 'every single one of those million tickets' in ONE DAY.

One day!

*'Wine and Wet Wipes'will never be the title of a Bruno Mars albumbecause the world is cruel and unfair.
