Lady GaGa was given a nasty shock while filming her new music video when she was reportedly bitten by an animal on the set.

The pop superstar has been filming the promo for her latest single, G.U.Y. (Girl Under You), at California's Hearst Castle and is said to have brought in a number of exotic creatures to take part in the filming.

The trainer on the set reportedly provided a slow loris, a baby kangaroo and an exotic goat, but none of the creatures were used in the shoot after Gaga was bitten.

The singer was nipped by the slow loris as she handled the animal, according to New York Post gossip column Page Six.

A source tells the publication, "The slow loris is the cutest creature on the planet, and Lady Gaga wanted to use it in one scene, but it nipped her. They put it back in its box and took it away in disgrace."

However, the star wasn't badly hurt and was able to laugh off the incident. The source adds, "She just laughed about it. She was a good sport."
