A new episode of “Carpool Karaoke: The Series” is set to debut on Tuesday, featuring a pair of big stars hitting the road while singing their favourite tunes.

These stars are “big” in more than one sense of the word: WWE champ John Cena and former Lakers great Shaquille O’Neal, who cram their ginormous frames into a tiny compact car.

In this new promo for the episode (above), the pair are seen driving in far roomier Cadillac SUV, and make up their best nicknames for each other (Cena gifts O’Neal with “The Empire Strikes Shaq,” who counters with “Cena Turner”).

In addition, this week’s episode also features “Good Morning America” personality Michael Strahan, with the former NFL star teaming up with NASCAR legend Jeff Gordon, and the two talk about Strahan’s thwarted ambitions to be an underwear model, Gordon’s various product endorsements and other topics (below).
