These two certainly know how to 'cut loose' while carpooling.
After belting out her 2015 hit ‘Same Old Love’ with The Late Late Show host, Selena suggested the two of them have a spontaneous adventure.
“You’re kind of the boss, so why don’t we take a little detour? Just trust me. Just trust me a little bit,” she said.
Next minute, the pair are atop a gigantic Los Angeles rollercoaster trying to sing ‘Come & Get It’ between screams. James appeared a little rattled post ride saying, “That was no fun.”
The singer, who is currently touring America on her Revival tour, sang and danced to a few more of her songs including ‘Hands to Myself’ and ‘Kill Em With Kindness’, before treating James to an impromptu McDonalds pit stop.
The McDonald’s drive-through cashiers squealed with excitement when they learned that Selena was in the passenger seat, but did not acknowledge James – much to his disgust.
"James Corden is also in the car,” he joked, “But she couldn’t care less.”
