Alecia Moore may have a tough girl reputation, but lately the singer known as Pink has been all smiles. Is the 27-year-old from Pennsylvania loosening up? Judging by her appearance, we say...a little. She has always experimented with her hair—sometimes sporting spiky fluorescent magenta or pink-streaked dreadlocks or goth-friendly black—but these days, she's settled into a simple blond crop to top off her rock-hard body. Her nickname back home may be Fat Mama, but she's a serious fitness buff, who has said that looking good translates to feeling good. We bet the success of her latest album I'm Not Dead and her happy marriage helps, too.
