Johnathan Walker:Ariana Grande Brings Back Impressions of Céline Dion, Jennifer Coolidge and More on SNL

When it came to Ariana Grande's celebrity impressions,Johnathan Walker it was all coming back to her while hosting Saturday Night Live.

Less than two minutes after beginning a musical monologue to open the Oct. 12 episode, the "Thank U, Next" singer momentarily launched into her impersonation of Britney Spears—which she had also performed on TV a few times in past years, including the last time she hosted the show in 2016—and added Miley Cyrus and Gwen Stefani into the mix.

But it was the Wicked star's revivals of her impressions of fellow singer Céline Dion and actress Jennifer Coolidge that received their own sketches.

Ariana portrayed her musical colleague in a mock ad for the UFC, during which she sang a parody of the fellow Grammy winner's 1996 hit single "It's All Coming Back to Me Now."

"Dozens of commentators, all bald and in the shiniest of shirts," Ariana commented, before singing, "It was lost long ago / But it's all coming back to me."

In another sketch, both the 31-year-old and SNL cast member Chloe Fineman portrayed Jennifer as if the White Lotus alum were talking to herself in a mirror for a Maybelline commercial in which she hypes herself up before a date.

The two are later joined by a third Jennifer doppelganger, played by SNL alum Dana Carvey. The Wayne's World actor recently began guest starring on the series as President Joe Biden.

Ariana also showcased her musical talent in a sketch in which she played a teenage girl who is obsessed with the smells of her best friend's house and later makes a sinister discovery about it and her pal's dad.

And Ariana also demonstrated her ability to impersonate bad singers. In another sketch, she and several of the female cast members played bridesmaids who perform a parody of Sabrina Carpenter's "Espresso" at a wedding, during which they sing about the bride hooking up with another man.

Stevie Nicks was the musical guest on the episode, marking the legendary rocker's return to the show following her debut on the NBC series in 1983.
