The actor was promoting the latest season of his TV series Episodes on late-night show Conan in January (15), when he joked about a meeting with the brothers - but Brits took him seriously.

LeBlanc said, "I went to this exhibition polo match one time and the princes were there and they were playing, and afterwards there was this big line to go and meet them... All they want to know is, 'When is the Friends reunion?' I told them to f**k off."

Returning to Conan O'Brien's chat show on Monday (10Aug15), the actor said he was grilled by the British media this spring when he was in the U.K. promoting his series.

He said, "It was the first question. It was 10 days in a row of interviews all day long to launch the show and every asked, 'So why did you tell the princes to f**k off...?' I was like, 'It was a joke. I never said that. They're bigger than me... and that would be rude.'"
