Lee Ann Womack will be participating in the "Top of the Charts" edition of ABC's "Who Wants To Be A Millionaire." The entire "Top of the Charts" edition of the hit game show will air over four episodes beginning with one on July 22.

Womack says that she enjoyed her time on the game show, but that the most difficult part for her was the "Fast Finger" rounds in which players compete against one another in a bid to be the contestant questioned by the show's host Regis Philbin.

he only thing I wasn't prepared for was how hard it was to punch the 'Fast Fingers' panel," she said. The singer admitted that the buttons were so hard to push that even when she thought she had pressed in the right answers, she found that the buttons had not registered her guesses.

almost wanted to punch those buttons, but it seemed too insane, like some mad woman beating the little panel to death. So I did the best I could, but it really slowed me down! I'd make a joke about worrying about breaking a fingernail, but that wasn't the case at all. I just couldn't hit those buttons hard enough."
