The Broadway singer and dancer stars in the WB sitcom "Nikki."

Ballet With Burn: My friend Sophie turned me on to this class CARDIO BARRE®. this place that does it, in Studio City, may be the only one. It’s a ballet barre warmup, only it’s a cardio workout, so everything you do feels like it’s going to kill you. I don’t know why, but the teacher, Richard, seems to pick on me a lot. I thought I was in shape until I took that class. I hate to exercise but I love to dance, so it’s the perfect combination. If I go to that class, I’ve earned the rest of my weekend.
