Elliot Page claims he had sex with his Juno co-star 'all the time'

Elliot Page has opened up about the connection he had with one of his Juno co-stars.

The film helped catapult the actor into stardom as he starred in the titular role about a teenager who gets pregnant and has to handle putting the baby up for adoption.

While he had appeared and starred in several films before the 2007 movie, Juno helped him become a household name.

The 36-year-old has written a memoir about his life and Page Six has obtained an excerpt that detailed an off-screen romance Page had with one of his co-stars.

"I was taken aback the moment I saw Olivia Thirlby. She seemed so much older, capable, and centered," Elliot writes in his memoir, titled Pageboy, despite them being the same age.

“Sexually open, far removed from where I was at the time. But the chemistry was palpable, it pulled me in."

Olivia played Juno's friend Leah in the film and they shared several scenes together.

However, it seems like they were more than just friends when the cameras stopped rolling.

Page recounted how they spent loads of time together.

During one of their hangouts, Thirlby 'looked directly at me and said point-blank "I’m really attracted to you"'.

"At that we started sucking face,” he writes in Pageboy.

“It was on.

“I had an all-encompassing desire for her, she made me want in a way that was new, hopeful. It was one of the first times someone would make me c*m, the first time I would open up."

Elliot said they would have sex 'all the time' and managed to find a few places to do it.

“Her hotel room, in our trailers at work, once in a tiny, private room in a restaurant," he said.

"We thought we were being subtle.

"Being intimate with Olivia helped my shame dissipate. I didn’t see a glint of it in her eyes and I wanted that — done feeling wretched about who I am."

UNILAD has contacted Ms Thirlby's management for comment.

Elsewhere in the memoir, Page opened up about having a relationship with Kate Mara, who was with The Social Network star Max Minghella when Page caught feelings.

The relationship came to be in 2014 when Page was busy filming the 2014 superhero movie X-Men: Days of Future Past.

“The first person I fell for after my heart was broken was Kate Mara,” Page writes in his book per PEOPLE.

“She had a boyfriend at the time, the lovely and talented Max Minghella."

It is unclear whether there was any crossover between Mara’s relationship with Minghella and Page, however, the Umbrella Academy star said Mara told him: “I never thought I could be in love with two people and now I know I can.”
