Rihanna Single? RiRi and Lady GaGa collab?

Yesterday, Jay-Z was in Paris promoting ‘Blueprint 3′  in France where he said that Rihanna was single.

A rumour started with a Lady GaGa facebook account saying she would be working with RiRi. (not sure if this rumour is true but it’ll be great if RiRi and Lady GaGa could collab)
