Jason Derulo became the latest celeb to jump into James Corden's SUV and join him for a spot of Carpool Karaoke on Wednesday, Nov. 4 — and it's unmissable viewing!

The hit R&B singer took the British show host on an unforgettable journey on The Late Late Show, where they talked sex, threesomes (or fivesomes...), sang opera, and even hijacked a Hollywood Star Tours bus!

To start off, Corden asked his guest about his penchant for talking dirty. Derulo revealed he actually used to be totally silent during sex, until one of his girlfriends called him on it.

"One girl told me that it was weird," Derulo explained, before admitting that these days he's very vocal in bed with girls.

"What's the most people you've ever had sleep in your bed?" Corden asked, wide-eyed.

"I'd say five, including me."

"You must have a huge bed?" marveled Corden.

"My bed is circular," he revealed.

Corden then asked his guest about his classical voice training, and persuaded him to give viewers a taste of his opera singing abilities.

Watch the whole amazing video above and see the moment Derulo taught Corden how to pick up girls with his dancing in a gas station, and then proceeded to hijack a Star Tours bus!
