Spears — who is about to release her new album, Glory — sings Toxic with Corden during the car ride. Corden also asks the Make Me singer about her two sons and if they’ve ever watched her perform in Las Vegas. The topic prompts Corden to tell Spears about the time he saw his mom in her underwear when he was about 11.
“I can’t shake the image from my brain,” he says.
