Rihanna left U.K. TV presenter Jonathan Ross red-faced after dancing suggestively for him on his hit talk show.

Rihanna walked off the performance stage while singing her track Talk That Talk on The Jonathan Ross Show and strutted over to the host's desk to show off her sexy moves.

The R&B star, clad in a miniskirt, gyrated her hips and bent over while Ross jokingly covered his eyes with his hands.

Earlier in the show, which aired in the U.K. on Saturday (03Mar12), Rihanna defended her racy dancing as part of her Barbadian culture.

She told Ross, "I don't really ever notice it, or think about it, until the feedback. It really made me think about this for a long time as to why it is this way, why people find it so sexual, but going back to Carnival in Barbados, the Crop Over (festival), this year I really notice that it's a cultural thing. It's the way we move... You can see me... half-naked, having a good time... all that good stuff.

"I've come to a place where I've earned the right to be OK with my artistry. You have to accept not everyone is going to interpret it the way you do. I always stay true to the message in the song, the message that I'm trying to get over with the visual. A lot of the time the music videos are banned, but you can't let your art suffer for that. You have to accept people have their own standards."
