The "Dancing with the Stars" contest is so scorching that A-lister Celine Dion, who performs on today's results show, longs to do more than sing for it, media reported yesterday.

Last week after taping her appearance, which includes a production number built around her signature song, "My Heart Will Go On," Dion's eyes were wide with enthusiasm for the hoofers, who include Jonathan Roberts, paired with Marie Osmond; Melanie Brown's partner, Maksim Chmerkovskiy; and Julianne Hough, dancing with Indy 500 champion Helio Castroneves. She's a "tremendous fan" of the show, she said.

The ABC show averaged about 20 million weekly viewers for each of its twice-weekly episodes in the 2006-07 season, eclipsed only by Fox powerhouse "American Idol." "Dancing" is still on its toes, with nearly 22 million viewers making it last week's No. 1 show.

"Dancing with the Stars" ups the kitsch factor for the finale, with a slew of glittering disco balls and gold-tinged decor that's a match for the wonderfully cheesy mirrored-ball trophy awarded to the winner.

Viewers got an extra splash of sexiness in this edition of "Dancing," courtesy of Brown, aka Scary Spice, and partner Chmerkovskiy. Last week, she took to the dance floor with her voluptuous figure clad in a skintight costume and whip in hand. Chmerkovskiy made no apologies for their bold style. Even family-friendly Osmond got mildly risque in a mambo last week. Part of her skirt was playfully ripped off by partner Roberts, exposing more than a bit of Osmond's leg, and she returned the favor by grabbing at his tear-away sleeves.

The skimpy costumes, a staple of the show, give pause to 93-year-old fan Julia Boes, who attended last week's performance. The Pasadena resident said that when her sister toured in the 1930s with the "Pretty Babies Revue," dancers "couldn't go out on the stage like they do now, with just a little bra." As for the dancing itself, "we didn't do like they do today, wiggle around and all that stuff," said Boes, who recalled foxtrotting in dance marathons. But the naughtiness hasn't deterred her from watching, she said.

Brassy Osmond, sultry Brown and revved-up Castroneves will face the music once more Monday as wraps another winning season.
