James Corden's Parents Jam With Metallica and John Legend Backstage at the Grammys

YouTube/The Late Late Show with James Corden

The pair also contemplate heckling their son, who hosted the awards show.

If you’ve ever wondered how James Corden got to be so funny, viewers of Thursday night's Late Late Show may have found the answer. On last night's episode, Corden aired a segment featuring his parents — Malcolm and Margaret — taking viewers behind the scenes at the Grammy Awards, and they did not disappoint.

The two lovably cheeky Brits are shown cracking a few jokes at their son’s expense and trying out a bunch of bizarre, very L.A. personal beauty products in the swag tent. At one point, the Grammy host's mother asks, “Are we going to heckle him? What should we say?” To which his father responds, “Get off!”

The jokesters learn how the stars achieve such glowing faces, grab half a dozen bottles of champagne and take a break to Hula-Hoop on their way backstage to hang with the stars before the show.

No one was safe from their jokes, not even those who couldn't make it, for obvious reasons. Passing a gold drum kit belonging to Prince’s backing band, The Revolution, Malcolm cracks, “That could be Donald Trump’s drum kit. But I wonder whether he could hold the sticks with his small hands?”

Because their anniversary happened to coincide with their son's big hosting gig, they were serenaded by Metallica and John Legend. Malcolm also played sax alongside Anderson Paak on drums, the couple interviewed Skrillex on the red carpet, and Malcolm grabbed kisses from every member of Cage the Elephant. And that was all before the show even started.

Watch their fun-filled adventure in the video below.
