Fans can expect at least one joke or sketch acknowledging Adele's eye-popping 100lb weight loss since the summer of 2019.
The video shows the other guests as well- Kate McKinnon and H.E.R. along with Adele.
In a teaser clip recorded at the studio based in the Rockefeller Plaza, New York, the 32-year-old looked sensational as her slimmed-down frame was put on full display.
"3 days to go ♥️", she excitedly captioned the photo, which showed the star rocking a Canadian tuxedo, a black face mask, and a pair of boots.
Adele first announced her appearance on the U.S. sketch show on Sunday admitting that she is both "so excited" and "absolutely terrified". In her caption above, she writes "3 days left" and asks a fan to comment on her post "HOW MANY UP TO THE ALBUM", a comment that now has 1305 likes.
Adele'shosting debut will come nearly 12 years to the day that she first appeared on the programme. "My first-ever hosting gig and for SNL of all things!" she wrote in a post on Instagram.
Adele teases Saturday Night Live appearance. But if there was ever a time for any of us to jump head first into the deep end with our eyes closed and hope for the best it's 2020 right?' "I love her SO much I can't wait to melt into a flaming hot mess when she performs, then confuse myself while I laugh my arse off in between it all".
It has been five years since the release of Adele's most recent album, the Grammy-winning 25.
H.E.R. then suggested it would be McKinnon who was performing and the Ghostbusters actress replied: "Yes me, it is I who will be musical guest this week".
The star kept her fans up to date with her significant weight loss following her divorce from husband Simon Konecki a year ago.
