Watch James Corden And Selena Gomez Turn Carpool Karaoke Into Roller Coaster Karaoke

"Why don't you have some fun before you go to work?"

Last night on The Late Late Show, James Corden welcomed Selena Gomez into the passenger seat for another fun installment of Carpool Karaoke. The pair sang along to some of Selena's greatest hits on the car radio, but it didn't take long for the star to suggest a change of scenery.

"You're kind of the boss, so why don't you just take a little detour for a second?" Selena asked when James said he had to get to work on time.

Selena's idea of a "detour" involved a roller coaster ride set to her song "Come & Get It."

Will Roller Coaster Karaoke become a new Late Late Show tradition? Fingers crossed.

All that excitement really worked up an appetite, so Selena and James made a pit stop at McDonald's to see if the cups really do have Selena's song lyrics on them. Turns out they do, but they had to hand back "Ain't No Mountain High Enough" and "Girls Just Want To Have Fun" first.

It's safe to say the employees were surprised to see them there.

Between songs, James made sure to ask Selena about Taylor Swift's squad and tried to angle for a membership. Unfortunately, it seems to be a girls-only club, although his performance of "Shake It Off" was certainly admirable.
