Sandra Bullock has shut down the rumors that her and Ryan Reynolds are dating.

When Bullock was quizzed about the rumors by the Today show's Al Rocker at the Golden Globes she said: "I think there will be a collective sigh amongst women across the United States when I say he's not my lover."

She added that the only man in her life at the moment is her adopted son, Louis, who will celebrate his first birthday this month.

Rumors that the on-screen couple were dating were rife after they rang in the New Year together in an intimate setting.

Ryan Reynolds is going through a divorce from his wife Scarlet Johansson, while Bullock divorces Jesse James last year.
