Britney has been on her best behavior lately and she was even rewarded with a girls' night out this weekend. She dressed tamely and so far no bad stories have surfaced. In fact, the latest news on Britney is that her big primetime appearance on HIMYM tonight is also going to be helping do good. Her cute Juicy and Nannette Lepore outfits will be auctioned off for an environmental organization. The six outfits worn by Britney will raise money for the Natural Resources Defense Council. In the rumor mill, the next step in re-building Brit's career is that she is opening up a dance studio called Basement. Many of you wouldn't let your kids take a lesson from Britney but we have a feeling there are plenty of other people out there who would sign up. All things are pointing in the right direction so fingers crossed her appearance tonight is a success.
