On Wednesday's show, Corden convinces the pop icon to jam out to her own song -- and it's awesome! "I'm not singing today. I was up all night," Carey says right before she starts belting out the first lines to the song. It's too catchy even for the diva herself!
The carpool sing-along didn't stop there. The duo also performed (in the car) "Fantasy," "Vision of Love" and "Thirsty." Impressively, Corden knew all the words.
Carey even got a little flirty with the 36-year-old host when he asked her how many No. 1 hits she had (she has 18). "You're so hot. Stop it," Corden said when she took off her sunglasses and gave him a sultry smirk. "I'm a married man. You've gotta stop what you're doing, cause I know exactly what you're doing. Oh my goodness. I can read you like a book."
Sadly, Corden and Carey did not cover "All I Want For Christmas Is You."
