Brook plays a Women's Institute member who appears nude for charity
Posters promoting a play starring actress Kelly Brook have had to be changed because buns covering her breasts were deemed to be too small.
The posters for Calendar Girls featured a nude photograph of the star holding iced buns up to her chest.
Transport for London (TfL) demanded the buns be enlarged before allowing the poster to be used in Tube stations.
The play's producer David Pugh said: "We've found ourselves in the world of censorship, we're in 1960s Russia."
Brook plays the role of Celia in the West End play, which tells the story of Women's Institute members who decide to bare all for a charity calendar.
The original calendar sold 800,000 copies worldwide. The story inspired the 2003 film on which the stage play is based.
Mr Pugh said he found TfL's decision "incredible" and said similar shots of cast members Jerry Hall and Gaynor Faye were used in previous posters.
"Someone is sitting in a dark room somewhere peering at any sort of nudity," he said.
"The whole truth of the story that I'm doing is about this group of ordinary women who did something extraordinary. I'm replicating what they did."
Mr Pugh added: "They said we were trying to titillate Tube travellers, I thought it was a joke.
"I don't know what the buns would be in bra sizes but we've gone four sizes up."
A TfL spokesman said: "We worked with the advertiser to ensure that the advert complied with our policy.
"We will be carrying an amended version of the advert on the Tube network."
Fittingly, one of the most memorable lines in both the film and play is uttered by Chris, the driving force behind the calendar, as preparations are made for the naked photo-shoot.
"We're going to need considerably bigger buns."
