Entertainment TV 'DWTS' ' Sailor Brinkley-Cook Says Dancing Has Helped Overcome Insecurity: 'I Feel Like a Machine' The 21-year-old model is competing with pro Val Chmerkovskiy By Christina Dugan Ramirez Christina Dugan Ramirez Writer-Reporter, TV People Editorial Guidelines and Aurelie Corinthios Published on October 1, 2019 10:14 AM Share Tweet Pin Email Sailor Brinkley-Cook didn’t expect to be competing on this season of Dancing with the Stars, but needless to say, the experience has been a formative one so far. Just days before the season premiere last month, the 21-year-old model stepped in to take her mom Christie Brinkley‘s place in the competition after Brinkley, 65, fell and broke her arm in two places during rehearsals. Speaking to reporters after her performance Monday night with pro partner Val Chmerkovskiy — a tango that earned 23/30 from the judges — Brinkley-Cook, who said she “grew up very insecure,” opened up about how dancing has helped her build confidence. “I grew up very doubtful of myself in a lot of ways and I went into modeling, which is … the most challenging think to take on as someone who is quite insecure,” she began. “But you know, you find your way in it, you find your groove in it, and I ended up loving it.” Allen Berezovsky/Getty “But doing dancing, oh my gosh,” she continued. ‘Showing up to rehearsal every day and being able to really work my body to the bone, to really try and improve in a physical and athletic way is so rewarding.” “It also makes me feel a lot better about myself because I feel like a machine,” she added.
