As you can imagine, the girls were stoked by the stars impromptu performance, and took to twitter to give her a shout-out.
Mel C re-tweeted the vid with a bunch of love heart eyes emojis, while Geri simply said "Go Adele."
It’s not the first time the group have shared their love, either.
When Adele sang their tunes during her Carpool Karaoke appearance with James Corden, the Spice’s were quick to let the star know their feels. While most of the girls re-tweeted the vid with a sweet caption, our personal fave was VB.
These girls are seriously squad goals, maybe they can come out as surprise guests at Adele's next concert ala Taylor Swift? We can only dream!
