Watch Kelly Clarkson's October 13, 2023 Appearance on The Tonight Show

She's back! Singer, The Voice alum, and talk show Host Kelly Clarkson was the October 13th guest on The Tonight Show Starring Jimmy Fallon.

Clarkson's Tonight Show visit came just ahead of The Kelly Clarkson Show Season 5 premiere on Monday, October 16. Clarkson and Jimmy Fallon are now neighbors, as Clarkson's moved her talk show from the West Coast to New York City's 30 Rockefeller Plaza. 

Fallon and Clarkson have created some supremely memorable music moments on TV in the past, from their Sonny and Cher cover to Clarkson and Ariana Grande's jaw-dropping "Mixtape Medley" showdown on Fallon's That's My Jam game show. Here's what happened during the October 13th appearance.

Watch Kelly Clarkson perform "lighthouse," a song from her album, Chemistry, during her Tonight Show appearance on October 13th.  

Kelly Clarkson: lighthouse

"[The album is] called Chemistry because I was trying to find a word—also, [it's] one of the songs on the album—but I was trying to find a word that really described the whole thing," Clarkson said about the record. "Because I didn't want everyone to think I was just coming out with some, 'I'm angry, I'm sad' [album], just one or two emotions. This album is definitely the arc of an entire relationship. A whole relationship shouldn't be just brought down to one thing. So there's the good, the bad, and the ugly kinda thing going on. Chemistry can be a really amazing sexy, cool, fun thing, but it can also be very bad for you. So that's why I named it Chemistry. I thought it was the perfect title to describe the entire album."
