Bo Derek gets candid with ET’s Deidre Behar in a wide-ranging interview. The actress opens up about her 18-year romance with John Corbett, including the secret to their long-lasting relationship and why they haven’t gotten married. In a nod to John’s role on ‘Sex and the City,’ Bo weighs in if she’s Team Big or Team Aidan! Bo also recalls her career-defining role in ‘10,’ which made her a sex symbol. She shares what it was like to shoot to stardom overnight, if she has any regrets about wearing cornrow braids in her memorable scene on the beach and how she feels about Kim Kardashian paying tribute to the hairstyle. Bo also talks about the recent documentary about her life and what it meant to have Linda Evans’ participation. Bo admits she will ‘never forgive’ herself for playing a role in breaking up Linda’s marriage to director John Derek, who left Evans for Bo when she was still a teenager. In Bo’s latest role, she stars opposite Jon Voight and James Caan in ‘JL Family Ranch: The Wedding Gift,’ which premieres Sept. 27 at 9 p.m. ET/PT on Hallmark Movies & Mysteries.
