"I've taken my cue from people here and from viewers, especially [cancer] survivors . . . who said, 'When it's time to literally flip your wig, you'll know,' " Roberts said. "I am not my hair," she said, quoting from the song by India.Arie. "I am the soul that lies within and that's it - no more wig. That's it." Roberts will auction her wig to raise money for a charity that helps "those who don't have insurance and can't afford this." [NYP]
