After trading her long brown locks for a platinum hairdo last year, singer Katharine McPhee found that even longtime friends don't recognize her, she said on 'The Rachael Ray Show' (weekdays, syndicated). And, she added, blondes don't necessarily have more fun.

"Born as a brunette, I will say that brunettes can give a blonde a run for their money," McPhee said. "I don't want to give the blondes too much credit for having all the fun. I think just changing your hair no matter what color it is, you have a good time doing it."
