The 36-year-old appeared shocked as she interviewed New Zealand model Zoe Brock as she spoke about an alleged assault.
Zoe said she hadn’t broken her silence and instead had been talking about her alleged ordeal for the past 20 years and even after the day it happened.
“I was alone with Weinstein and he very quickly left the room and came back naked,” she told Holly and co-host Phillip Schofield.
Holly Willoughby responded, seemingly shaken, as she said to Zoe: “That’s where this horror unfolded in front you, you told him you felt very uncomfortable, you told him you felt tricked.
“You tried to work out the best thing to do for your own safety and you need up locking yourself in the bathroom where he was hammering on the door, which must have been frightening.
Zoe said that she had got “angry and focused” and ended up scolding the producer until he relented and she eventually left the bathroom.
When asked by Phillip, 55, about how relieved she felt now that allegations had finally started to come out, she said: It’s amazing. I heard that night about Gwyneth. People knew. Who am I?
“I’m just a model from Australia and New Zealand. I’ve known that Gwyneth was assaulted for 20 years. A lot of people knew.
“Shame. Shame on all those people who knew those secrets and did nothing.
