Kelly Clarkson changed key lyrics during a performance of “Abcdefu” to seemingly shade her ex-husband, Branson Blackstock.

On Thursday’s episode of “The Kelly Clarkson Show,” the “American Idol” alum added her own twist on the hit song’s chorus appearing to use inspiration from her own tumultuous split.

“Forget you and your dad/ And the fact that you got half,” Clarkson, 40, sang. “And my broken heart/ Turned that s—t into art.”

Gayle, 18, originally sings, “F—k you and your mom/ And your sister and you job / And your broke-ass car/ And that s—t you call art.”

Clarkson filed for divorce from Blackstock, 46, in June 2020 after seven years of marriage. Following an intense two-year battle over their assets, the pair settled their divorce in March 2022.

Clarkson eventually agreed to make a one-time payment to Blackstock of $1.3 million. He also received $46,000 per month in child support from the songstress and $115,000 per month in spousal support, which expires in January 2024.

The former couple also fought over their Montana ranch, which was ultimately awarded to Clarkson.

However, Blackstock, 46, was allowed to live in the mansion temporarily if he paid the “Since You’ve Been Gone” singer $12,500 a month for rent.

Clarkson also received primary custody of their two children: daughter River, 8, and son Remington, 6.

If fans are lucky, Clarkson’s recent performance is just a taste of what is to come in her upcoming album, “Chemistry.”

Earlier this week, the “Breakaway” singer announced the new music — which took “close to three years” to finish — will be released “really soon.”

“This album is definitely the arc of an entire relationship … and a whole relationship shouldn’t be just brought down to one thing,” she said in an Instagram video. “So there’s, you know, the good, the bad and the ugly kind of thing going on in it.”

She also explained how her divorce inspired the title of the album, which will be her first traditional LP since 2017.

“I was trying to find a word that really described the whole thing ’cause I didn’t want everybody to think I was just coming out with some just like, ‘I’m angry, I’m sad’ — like just one or two emotions, you know?” she said.

“Chemistry can be a really amazing, sexy, cool, fun thing, but it can also be very bad for you,” she added.
