Kelly Clarkson performed her latest single, 'Mr. Know It All' for the very first time at the 'Stars for Free' music festival in Berlin, Germany on Saturday.

The pop star treated the 17,000-person crowd to her hit mid-tempo pop song, which she said she was "stoked" to sing for her fans. The single first premiered on Clarkson's website on Aug. 30, and is the lead track of her upcoming 'Stronger.'

Clarkson's first live rendition of the tune was flawless. She is likely to have another moment of perfection when she performs the song again at the upcoming iHeartRadio Music Festival in Las Vegas, Nev. on Sept. 23.

The 29-year-old has already shot a music video for the song, which is expected to premiere on VEVO on Sept. 26. The footage was shot in Nashville, Tenn. and was directed by Justin Francis, but in a recent interview, the singer remained coy about its premise. “I don’t want to ruin the concept," she said.

Clarkson recently moved up the release date of 'Stronger' by one day to Oct. 24, and revealed plans to tour in January. Her first single 'Mr. Know It All' debuted in No. 30 on Billboard Adult Pop Songs chart just after its Sept. 5 release.
