Ariana Grande does a Celine Dion impression on "The Tonight Show Starring Jimmy Fallon" on March 20, 2015.

If imitation is the sincerest form of flattery, then these A-list pop stars should consider themselves very, very flattered. Of course, Ariana Grande made headlines just last week after she showed off her incredible impression of fellow diva, Celine Dion.

She's hardly the first star to put her spin on another star's swagger. She joins the likes of Adam Levine, Christina Aguilera and more, who have all had a little fun at their pop star contemporaries expenses.

Check out just a few of our favorites below.

Ariana Grande as Celine Dion

When the "Love Me Harder" singer appeared on Tonight Show on Mar. 20, she didn't have to try too hard to show off her Celine impression. Grande broke out the impression-- including Dion's signature chest thump-- when she busted out her take on Dion's duet with Peabo Bryson from Disney's Beauty and the Beast.

Christina Aguilera as Britney Spears

The world had been waiting with bated breath to hear Aguilera break out her best Britney Spears impression. Lucky for all humanity, that happened back in February when The Voice mentor appeared on The Tonight Show. Close your eyes and you might actually think that's Britney.

Nicki Minaj as Beyonce

She woke up like that. Well, it probably took a little hair and makeup to help transform the rapper into her "Flawless (Remix)" partner-in-crime. Still, she managed to show off her best Queen Bey impression when she appeared on SNL in 2014.

Miley Cyrus as Justin Bieber

When Cyrus stopped by Saturday Night Live in 2011, she perfectly put her spin on a swagged-out Justin Bieber, including his wink, hair flip and "cocky nod." Making the skit even more ridiculous, it was went down on the Miley Cyrus Show sketch with castmate Vanessa Bayer filling in as Miley, obviously.

Bruno Mars as... Everyone

It should really come as no surprise that a guy who got his start in show biz impersonating Elvis would have a killer repertoire of pop star impressions. When Bruno Mars hosted Saturday Night Live in 2012, he showed off that he can do just about anyone, including Steven Tyler, Bieber, Katy Perry and Michael Jackson.

Adam Levine as... Everyone Else

Not to be outdone by the "Uptown Funk" singer, when the Maroon 5 frotman appeared on the Tonight Show in 2014, he showed off his uncanny ability to impersonate some other chart toppers, like Frank Sinatra, Bob Dylan and Eddie Veder. Of course, he also had his own take on Jackson, which, honestly, basically just sounded like Adam Levine.
