Who knew Adele could rap?! Turns out there was way more to the British singing sensation's "Carpool Karaoke" session with James Corden than we expected!

Not only did the 27-year-old singer blast her way through some of her own biggest hits with the Late Late Show host, she also gave us a sneak peek at some of the other songs she likes to sing to when she's stuck in traffic.

The segment, which was filmed in London when both Adele and Corden were home for the Christmas holiday, is a 15-minute magical mix of the Grammy winner's top hits, some hilarious conversations (ever wondered what happens when Adele has a night out on the town and ends up getting a bit drunk?) and some unexpected musical treats.

"You were a Spice Girls fan?" Corden asked his guest halfway through the car ride.

"It was a huge moment in my life when they came out," Adele replied, totally seriously. "Girl power — five ordinary girls who did really well and got out. And I wanted to get out," she said.

Admitting that she always saw herself as Geri Halliwell, the singer then went on to do an awesome rendition of "Wannabe."

But if you think that was surprising, wait until you hear her truly amazing version of Nicki Minaj's "Monster," complete with every ounce of Minaj sass!
