Pink “Oprah” Performance Feb. 5 [“I Don’t Believe You” LIVE]

Pink gave a show-stopping performance with her ballad “Glitter in the Air” at the Grammys last Sunday. The performance featured the singer dangling upside down in the air, and at one point — dripping wet. Now Pink is bringing circus act to The Oprah Show.

The singer will perform an acoustic version of her hit track “I Don’t Believe You” during O’s weekly “Live-in-Chicago” special this Friday, Feb. 5.

In the meantime, Pink is using her Twitter page to shoot down rumors that she lip-synched her way through her performance last weekend.

“I hear there’s a debate over whether or not I sang live on grammies,” Pink Tweeted on Tuesday night. “I have never lip synched in my entire life. I’m 100% against it.”

The star performed the stunt nearly 160 times during her recent “Funhouse Tour.”
