The Jonas Brothers are one of the hottest acts around, with a huge amount of influence on teens and tweens, which is why the fact that they're actively talking about diabetes is such a big deal. Nick Jonas was diagnosed a couple of years ago, and instead of letting him get down about it, the brothers have used it as a platform to help others. That rocks!

Kate Hudson tends to look fabulous in whatever she wears -- haute couture, jeans and a tee, or a bikini. She doesn't just rely on genetics to keep her looking hot, though -- she incorporates all kinds of workouts into her fitness routine to stay in shape.

Everyone needs a way to get rid of their stress, and Raven-Symone is no different. The actress relies on boxing to keep her self-proclaimed "anger issues" at bay.

If you watched last week's finale of So You Think You Can Dance, you were probably as impressed as I was with Mary Murphy when she got out from behind the judges' table and did a hot ballroom dance with Season Two's Dmitry Chaplin (who, as I had hoped/expected, opened his shirt at the end -- man I've missed him!).

At 39 years old, Mary showed that she not only still had the moves, but the lady's got a body! And, apparently, that body is courtesy of doing the Core Rhythms program (a dance workout incorporating lots of Latin movements) every day. Mary lost 30 pounds in three months, dropping from a size 14 to a size 8.



She's also following a healthful diet, eating lots of veggies, chicken, and Egg Beaters. She's thrilled with her new body, and with the fact that she can wear short dresses again.
