The singer recorded the promo clip for her new Calvin Harris collaboration 'We Found Love' in a grain field just outside of Bangor in Northern Ireland.
Shots from the set see the 23-year-old dancing around the field in a red bikini top and jeans. However, at one point Rihanna reportedly removed the top and exposed her breasts.
The farmer who owned the land was walking to his tractor and caught sight of the popstar. He then decided to approach her and ask her to cover up as he deemed it "inappropriate".
Alan Graham told BBC News: "I thought it was inappropriate. I requested them to stop and they did.
"I had my conversation with Rihanna and I hope she understands where I'm coming from. We shook hands."

Graham explained that he didn't know who Rihanna was when he agreed for the video shoot to take place on his land.
He added: "I didn't know who was coming. If the name 'Rihanna' had been mentioned, well, no disrespect but it wouldn't have meant anything.
"From my point of view, it was my land, I have an ethos and I felt it was inappropriate.
"I wish no ill will against Rihanna and her friends. Perhaps they could acquaint themselves with a greater God."
Rihanna and Calvin Harris's 'We Found Love' is available to download in the US now and will be released in the UK in the coming weeks.
