Watch: Kelly Clarkson leads Meghan Trainor, Shaq and more through 'Since U Been Gone' mix on 'Fallon'
The Tonight Show Starring Jimmy Fallon YouTube

'Kelly Clarkson led an all-star lineup of celebs through an attempt to sing her empowering breakup anthem “Since U Been Gone” in an ear-splitting segment called “Turn It Up” on “The Tonight Show” last night (Jan. 7).

Clarkson kicked off the song with her stellar, signature vocals and then NBA star Shaq O’Neal really threw his heart into it, to disastrously adorable proportions. Fanboy Jimmy Fallon did a decent job with his part, followed by an enthusiastically out-of-tune Rachel Brosnahan and an even more sonically dire John Oliver. Fortunately, we got a bit of a melodic reprieve from The Roots. The sassy and soulful Meghan Trainor, pretty much schooled everyone on how the song should be sung (except Clarkson, of course!).

All the famous folks deserve props for accepting Fallon’s singing challenge come-what-way. Mumford & Sons also delivered a strong vocal showing. Overall, Clarkson will always reign supreme on the critically-acclaimed, Grammy-winning song which has become one of her signature hits.

To the other singers’ credits, some people just can't sing. But, they’re all extremely good at what they do. Consider Bronahan, for example, who just scored a Golden Globe Award for her incredible work on “The Marvelous Mrs. Maisel.” Shaq, after all, is Shaq! Basically, we can’t help but love them all for trying!

Kelly Clarkson is touring to support her album Meaning of Life in 2019, which includes a stop at the STAPLES Center in Los Angeles, California on Jan. 26 (Tickets). Stay tuned to AXS for more on Kelly Clarkson.
