Gwen Stefani joined James Corden on the latest Carpool Karaoke - but that's not even half the story.
The pair were accompanied along for the ride by two Hollywood giants, and it all got pretty phenomenal.
Stefani and Corden started the journey by singing a slew of the popstar's classic hits, including 'The Sweet Escape'.
Stefani then tried to teach the Late Late Show host the fast-speaking verse involving sour milk and shutting refrigerators, although he struggled like all of us.
The singer also talked about her love of emojis, doing some pretty ace impressions as well as cringing over the eggplant symbol.

Corden then called upon none other than George Clooney to join them for the ride, who in turn gave Julia Roberts a ring to make it four for the carpool.
The group all sang 'Hollaback Girl', Clooney interpreting what the hell the song may actually be about.
"'I ain't no hollaback' meaning if some guys are on a construction site and they're yelling at a girl, she's not going to turn back, she's not that kind of girl," he said, with Stefani saying he was "quite close".
However, the singer added that she would "never" disclose what the real inspiration was about, only revealing: "All I'll say is I won."
"This shit is bananas," Clooney joked.
After Clooney and Roberts revealed what their favourite movie lines were (because why not?), the group all did a spot-on rendition of Queen's 'We Are the Champions'.
Champions indeed.
