Harriet breaks silence over 'cosy night out' with Cate's husband

She went into hiding after being linked to Cate Blanchett's husband, Andrew Upton, and now Harriet Dyer has broken her silence about the allegations.

According to New Idea, the 27-year-old was overheard discussing the incident at the No Activity premiere last week.

"He's a notorious party boy - everyone knows that," the Love Child actress allegedly told a group of friends, including Offspring star Dan Wyllie.

The magazine reports that Harriet added that the footage, which saw herself and Andrew looking cosy during a night out in Sydney, "was just drinks after the show," and that while she wants to address the allegations, she fears doing so "just adds fuel to the fire."

New Idea, who first released the video footage of the pair, also claims Harriet was heard saying she'd spoken to the Carol actress about the recording, with apparently saw her holding hands with Andrew, who married Cate in 1997.

"I sent through an email to Cate and said: 'This is all s***,'" the mag says Harriet said.

"She wrote back: 'We're cool babe.' Pat's fine, Andrew's fine, I'm fine - Cate was the missing piece of the puzzle."

Surprisingly her admission that "Pat's fine" also seems to confirm her relationship with No Activity co-star Patrick Brammall, who was absent from the premiere despite starring in the series and being the show's co-creator.

Andrew, who was once the artistic director of the Sydney Theatre Company, spoke about his relationship with Harriet at the time of the incident.

"We've been good friends for years. She's a good friend," the 50-year-old said in the video footage.
