From tubby to trim, awful to awesome, head-case to hubba hubba, Britney Spears has been on a crazy journey over the last few years, but she's made a pretty spectacular comeback. She's looking great, her career seems to be back on track and she hasn't done any bizarre publicity stunts in ages. Does Spears credit her recent sanity to a good shrink or a stint in rehab? Nah -- in a recent interview, she admitted that dancing is the best therapy.

"Everybody has a world that they create around themselves. If I have a lot of nervous energy, when I start dancing it goes away and I just feel emotion. It's like a rollercoaster," says the songstress. "People think that if you go through something in your life you need to go to therapy, but for me art is therapy because you are expressing yourself in such a spiritual way."

Britney's definitely on to something here -- dancing is good for the soul and body. Plus it's a really fun way to get fit.
