In an interview with Entertainment Tonight published Thursday, the 62-year-old Dirty Dancing star revealed the advice Curtis gave her on how to best transform into the lead role for Lifetime biopic Gwen Shamblin: Starving for Salvation. One of the visual aspects of the Shamblin role is a distinctive teased, bleached-blond hairstyle. The first-time Academy Award nominee explained that Curtis steered her in the right direction to achieve this look. "She said, 'Well, you have to go with Rob Pickens. He's the best wigmaker. He just did my Halloween wigs [and] he did Ana de Armas for Blonde.'" Grey didn't argue. "When she tells me with that kind of stern voice, I do what she says, and so I called [Pickens]."
