"Can we come sing for you?'" Beckham recalls.
Just this morning, the next guest was revealed, and we definitely couldn't have predicted it. Joining James in the auto will be Victoria Beckham.
We can't wait to hear her renditions of our favourite Spice Girls songs!
Yesterday, the designer gave a sneak peak as she got her makeup done and then in the vehicle with James.
Mrs David Beckham shared scenes of herself filming Carpool Karaoke on Instagram stories.
Victoria will no doubt be singing the most famous tracks from her time with the Spice Girls, as well as her short-lived solo career, which saw her spawn just one hit - Out of Your Mind.
Known for always wearing high heels and dressing up for every occasion, Victoria Beckham shocks fans with a new, casual look.
Victoria Beckham is to revisit her music career on a future instalment of Carpool Karaoke.
Victoria joins the likes of Adele, Stevie Wonder and Mariah Carey who have appeared on Carpool Karaoke.
The Spice Girls formed in 1994 and released their debut single, Wannabe, in 1996.
Although the Spice Girls reformed for a performance at the 2012 London Olympics, amid reports of rifts between the former bandmates, Victoria vowed never to perform with the group again. "People think that I'm so miserable, so this is me having a bit of fun and laughing at myself", she says, referring to the T-shirt.
But despite all that, we're still crossing our fingers that her former bandmates Emma Bunton, Mel B, Mel C & Geri Horner may just make their way over to LA for a special appearance... You can see in the pictures shared by Victoria on social media the huge smile he has plastered on his face.
