ET was with "Dancing with the Stars" contestant Wendy Williams at her "top secret" rehearsal with professional dance partner Tony Dovolani. Although Wendy does acknowledge that "things ache when I wake up in the morning," she says has no major issues and feels she’s already getting into shape doing the cha-cha and other dances. "I don't get on the scale, but I do sense a difference in my body in its most raw form, which is when I get out of the shower. There are also certain jeans that fit better, and my husband says I look good, so I feel good," Wendy said, adding that she's really looking forward to trying out different glittery costumes and wigs during the show.  Wendy, 46, says her biggest challenge is maintaining the rigorous practice schedule that goes six days a week and at the same time juggling the rest of her life, which includes a talk show, a game show and her husband and 10-year-old son. But Tony says he thinks she's doing great: "You know it's funny because she makes me laugh a lot, but when it comes to work time, she's very serious about this. She wants to give it her all. So we work really hard, when it's time to joke we joke, when it's time to work we work." (ETonline.com)
