Vivacious talk-show giant Wendy Williams will try her two-step as a contestant on “Dancing With the Stars,” Page Six has learned. “The Wendy Williams Show” will go on hiatus while she participates next month. Ample-cleavaged Williams — who would no doubt look great in the show’s trademark sparkly outfits — has been critical of other contestants on the dance competition, especially wooden Kate Gosselin,who she said “dances awkward and horrible.” But towering at 5 feet, 11 inches without heels and with even bigger hair, Williams will need a powerful partner to whirl and twirl her. Her rep told us, “We have no confirmation on that.” A rep for Williams’ show said, “Production hasn’t added any last-minute or unplanned hiatus days to the schedule.”
