After receiving backlash from an animal rights group for drinking a glass of donkey semen, contestants Claire Odioso and Bryne Odioso have allegedly been told to keep their mouths shut by NBC.

Claire reportedly got a call from the executives of the show because of a video of her talking about the episode on TMZ's website, defending her actions and clarifying that there was no animal pornography involved, as her critics had implied.

There's a large difference, no sexual acts involved, Claire announced on TMZ.

We feel no animals were harmed during the stunt, and it is known that animal semen is consumed in parts of the world like Australia and New Zealand, Brynne told Patch.com.

The twins have expressed that they are not ashamed of their actions, and are proud of their achievements, even though the episode was not aired. The episode, entitled Hew Haw, Hew Haw required the girls not only to down a glass of donkey semen, but also a glass of donkey urine.
