Margot Robbie offered over $500,000 for pictures of her feet

Barbie actress Margot Robbie has been offered over half-a-million dollars for pictures of her feet. 

Fun with Feet, an online platform where people buy and sell their foot imagery, has reportedly proposed an eye-watering payment of NZ$537,650 for pictures of Robbie's tootsies. 

The Daily Mail reported she'd been sent a formal letter which made the offer.

"Dear Margot, My name is Liz and I make thousands selling feet pics on Fun With Feet," it began, according to the outlet.

"I would love to collaborate with you on some Barbie-inspired content that'll earn us both millions. Plus, Fun with Feet are offering to pay you £250K (NZ$537,650) as a starting bonus.

"If I'm right, we'll be able to capitalise on our likeness - and the world's obsession with all-things Barbie - to no end, all thanks to our feet!"

"Liz" also made the offer to Ryan Gosling, who plays Ken in the hit film. Neither he or Robbie have publicly responded to the request.

Robbie, however,  is aware people have been asking about her feet for years.

In an interview promoting Barbie, she said she was "flattered".

"I have to say I'm really flattered that people are excited about my feet - I think that's lovely," she said.

"I've been lucky to have been in some iconic films, but there's been some shots of my feet which I think has only encouraged this notion."

While accepting a Screen Actor's Guild award for Once Upon a Time in Hollywood, Brad Pitt made a point to shout-out Robbie's feet during his speech.

"I want to thank my co-stars Leo, Margot, Margot Robbie's feet," he said at the time.

Earlier this week, Variety said the Wolf of Wall Street actor will net a tidy US$50 million (NZ$83.67m) in salary and box office bonuses for her part in bringing Barbie to life, according to three individuals with knowledge of her deal.

As well as acting in the film, Robbie was also a producer.
