Rihanna Debuts Wild New Hairdo in HollywoodOnly weeks after reverting to her natural color, Rihanna's red hair is back, and this time, it's bigger than ever.

The 'What's My Name' singer stepped out in Hollywood last night sporting a larger-than-life crimson wig, similar to the red curls she rocked at November's American Music Awards.

The style chameleon, whose edgy style has inspired countless imitators, first made hair headlines when she chopped off her long locks in favor of a face-framing crop in 2008.

The singer's penchant for tight clothes and tattoos has turned the heads of not only fashion insiders, but her fair share of celebrity admirers as well. Celebrity stylist Philip Bloch named Rihanna a top style star of 2010, saying, "Rihanna just brings you the fashion. She brings you designers. She brings you pink hair."
