The star almost gave fans an accidental sneak peak ahead of the movie's release this week
Dakota Johnson will set heartbeats racing when Fifty Shades of Grey is released this weekend, but she nearly gave fans a sneak preview in a plunging dress at the world premiere.
The brunette beauty - who plays Anastasia Steele in the adaptation of E.L. James' erotic novel - risked a nip*slip on the red carpet as she bared a cleavage in a very revealing gown.
The star wore a huge smile - but no bra - at the huge event to unveil the blockbuster ahead of its full release in time for Valentine's Day.
Speaking at the Fifty Shades world premiere, the star told reporters that she has no "expectations", but hopes people enjoy the film.
She said: "This is so crazy. I’m just trying to be cool. My expectations? I don’t have any. I just really hope they like the movie."
Meanwhile, co-star Jamie Dornan added: "We're proud of it, we want people to see it."
Actress Dakota is gearing up for the release of the BDSM-themed movie, and she recently admitted she became "detatched" as she and Jamie Dornan filmed their sex scenes .
She told The Telegraph: "It was like watching someone who looked a lot like me doing really bizarre things."
