Dustin Hoffman has revealed that he was bitten on the nipple by a guinea pig during press rounds for his latest film.

The actor said that a recent attempt to keep himself and journalists entertained while promoting The Tale Of Despereaux backfired when the animal hidden in his pocket became aggressive.

He said: “You feel like it’s presidential, and it’s kind of silly. So for Despereaux… I rehearsed with the guinea pig and everything – it was doing great.

“I took it to the press conference and suddenly it bit my nipple. I haven’t lactated since.”
