Actress and singer Gwyneth Paltrow has sparked a touchy debate and received much criticism when she tweeted the n-word while at a Watch the Throne concert.

She got the opportunity to be on stage with Jay-Z and Kanye West Friday night as the two superstar rappers performed their smash hit "N*ggas in Paris".

It was then that she took to Twitter to let near one million followers know what she was up to.

She tweeted "Ni**as in paris for real @mrteriusnash (the dream) tyty, beehigh", along with a photo of herself on stage with the two rappers.

Do you think she crossed the line with her tweet, or is it cool because it's the title of the song?
