Dakota Johnson shares feelings about ‘straddling’ Justin Timberlake in intimate The Social Network scene

Dakota Johnson opened up on her experience in iconic film The Social Network, particularly opening up about her intimate scene with pop star Justin Timberlake.

The 2010 flick has been one of the best-received films of the last 15 years, resulting in eight Oscar nominations and being nominated as the best film of the year by the National Board of Review.

Directed by David Fincher and starring the likes of Andrew Garfield, Jesse Eisenberg and Justin Timberlake, it's no wonder that it was a box-office hit.

The title is based on a book called The Accidental Billionaires by Ben Mezrich, which looks at the rise of social media giants Facebook, and the roles of those involved.

Following the co-founders of the site in Mark Zuckerberg (Eisenberg) and Eduardo Saverin (Garfield), the title follows the journey that the pair take to the top, and all of the troubles that come with success and money.

Timberlake plays Sean Parker, a co-founder of Napster, who becomes increasingly involved in Facebook as the film goes on, but he first appears on our screens following a one-night stand with college student Amelia Ritter, played by none other than Dakota Johnson.

Reminiscing on a number of her classic roles in a new video with Vanity Fair, she re-watched the scene in question and explained her 'preconceived notions' of performing with the 'Mirrors' singer.

When asked about if she, 19 at the time, had any prior thoughts to filming with the star, Johnson replied: "Are you kidding? I was just like 19 and straddling Justin Timberlake and like whipping him in the face with my hair. 100 per cent had preconceived notions, but he was lovely and kind and really welcoming for a person that was just a stranger."

The Fifty Shades star also opened up on Fincher's particular directing style, explaining: "I think that because this was 'The Social Network' and David Fincher, we did this so many times that I'm like, I'm in it. I know it, I know all the lines. It's still there.

"We did it so many times that I feel like I remember this and it's happening now. Maybe I was traumatised," she joked.

Now engaged to Coldplay lead singer Chris Martin, the 34-year-old previously touched on her experience on set with Eisenberg and Garfield, revealing in a conversation with the former: "You and Jesse were so busy on that movie, and I was obviously in it for four seconds, but I spent a few days on set just watching.

"I remember sitting down with you guys when you were having lunch one day, and you asked me loads of questions. You were really nice - and Jesse didn't acknowledge me. He was probably in character," she recalled.
