Kelly Clarkson just celebrated the “best birthday” she has “ever” had while hosting The Kelly Clarkson Show by embracing an opportunity to harmonize with Ann and Nancy Wilson of Heart.

The former American Idol winner, who turned 42 on Wednesday, April 24, invited the Wilson sisters onto her show for a special “Kellyoke” performance to celebrate her birthday. As the rock and roll stars dusted off some of their band’s biggest hits for the daytime talk show’s stage, Clarkson appeared especially thrilled to take on the lead vocals as they played “Crazy On You.”

For their performance of the song, Nancy strummed her acoustic guitar, and Ann, who typically sings lead, sat listening and bobbing her head along to the rhythm as Clarkson belted out the lyrics. As shown in a video clip of the performance that the “Because of You” singer’s NBC show later shared on Instagram, Ann was grinning and clapping as Clarkson ended the performance.

“This was the best birthday ever on this show—ever,” Clarkson said in behind-the-scenes footage of the performance.

As fans have pointed out countless times before, there doesn’t appear to be much that the “Since U Been Gone” singer cannot sing well. Viewers agreed that Clarkson’s “Kellyoke” version of “Crazy On You” served as another example of her masterful singing skills, with one fan declaring that they “love Kelly in fangirl mode.”

One fan begged for Clarkson to “put this out on an album,” while another said that people “couldn’t ask for a better” musical collaboration.

“Kelly can sing anything,” one Instagram user wrote, adding that the “Stronger” singer has a “versatile and effortlessly flawless voice.”

“Kelly that was awesome!” another fan commented. “You can sing anything! To take on Heart like that and sound just as good- is a true feat! Loved it!”
