The Biggest Loser @ 8pm
The players have been working their butts off (literally) and are feeling pretty good about their progress. Tonight, style guru Tim Gunn is going to make them look pretty, too, with hip hairstyles and flattering fashions to show off just how much they've taken off. In addition, a treadmill challenge has two contestants showing off their commitment and can-do attitude — and their competitive spirit, which keeps them going for more than an hour.
One Tree Hill @ 9pm
The show celebrates its 100th episode with a fittingly momentous occasion: Lucas and Lindsey's wedding day. It looks to be a joyous event for all — well, maybe not for everyone. Peyton made peace with Lindsey, but will she now forever hold her peace as she witnesses her true love, Lucas, marrying someone else? Or maybe Haley will say something, since last week she suddenly told Lucas, "You can't marry Lindsey." Whatever happens, it will surely be a memorable day in Tree Hill.
The Riches @ 10PM
When we left Eden Falls last year, Dale, who's not quite as dumb as he looks, was on the verge of stumbling onto the truth about the Riches. He puts the pieces together on tonight's second-season opener, and he might strike it rich as well. It seems that Hugh has a new land deal brewing, and Wayne's (er, Doug's) share could be $13 million. And, since Wayne and Dale each has damaging information on the other ("mutually insured destruction," Dale calls it), they're 50-50 partners. Meanwhile, Dahlia and the kids (and Cherien's senile mother) have hit the road, joined by Nina. "I want to live off the land," she tells Dahlia
Dancing With The Stars @ 9pm
Season 6 kicked off last night with the six male contestants, so tonight it's time for the women: Shannon Elizabeth, Marlee Matlin, Priscilla Presley, Monica Seles, Marissa Jaret Winokur and Kristi Yamaguchi. This show hasn't had a female winner since Season 1 (Kelly Monaco, back in 2005), so perhaps a little battle of the sexes could inspire one of these ladies to put an end to that streak.
