Los Angeles, CA (CNS) - Singer Fergie loves gymnastics and hates rumors. That's why performing a one-handed cartwheel on "Idol Gives Back" takes care of both the gymnastics, that she loves to do, and the rumors she is trying to squelch that she is pregnant.

Fergie told Ryan Seacrest on his KIIS-FM radio show that doing the cartwheel was a way to prove she wasn't pregnant. The pop star insisted to Seacrest that she is not pregnant and in fact upped her exercise regime before appearing on "Idol Gives Back."

On the show she performs with the group Heart, and during the performance lets loose with some gymnastic routines.

"Idol Gives Back" will air Wednesday on FOX.
