It's hard to resist singing along to a good Kelly Clarkson [1] song! On The Tonight Show Starring Jimmy Fallon [2] on Monday, a few celebrities belted out the lyrics to the singer's hit track "Since U Been Gone" for a hilarious video called "Turn It Up." While Clarkson (and her insane voice [3]) made a cameo in the video, it's stars like Shaq and The Marvelous Mrs. Maisel [4]'s Rachel Brosnahan that really stole the show as they tried their hardest to hit those crazy high notes. Let's be real: this is DEFINITELY how we all sound while singing in the shower.
