Heidi Montag and Spencer Pratt, who first found fame on the MTV “reality” show “The Hills”, admit they have become the go-to guys when a television show needs a villain or two.

The couple’s most recent foray into reality television was on the UK version of “Big Brother”, where they say they felt bullied by certain housemates and were genuinely scared to go to sleep.

“We didn’t sleep much at all. I always had one eye open. We were watching them thinking they were going to try and kill us in our sleep. We were constantly nervous something might happen. Every time we saw any of them near knives we left the kitchen straight away. Some of them would itch their own face with a butcher’s knife – it was mentally insane. If they’ll hold knives by their own faces I didn’t know what they were capable of,” Pratt said.

But he’s not afraid to admit that he and wife Heidi are sometimes held to a certain stereotype when they participate in these types of shows.

“They brought us in to be Speidi and stir it all up. I feel like a cartoon character. My talent for some odd reason, is being an a**hole,” he said.

But in the past, the couple has made it clear that they just want to be in the spotlight again. In 2011, after a disastrous bout of plastic surgery for Heidi and a sudden downturn in their popularity, the couple spoke openly about doing whatever they had to do to make money.

“If they called me right now and said, ‘We want you to be on ‘Jersey Shore’ and be a bully, and we’ll bring your paycheck back,’ I’d say, ‘Get me on a plane to Italy,'” Pratt said of MTV.

They might start to reconsider their image, however, now that their time on “Big Brother” has come to an end with death threats in hot pursuit. The couple so enraged fans of the show that many took to Twitter to voice their displeasure and have been reportedly threatening in nature.

“The American couple have become the most reviled contestants in the history of the show and Big Brother chiefs will ensure they get close protection from minders when they eventually exit the house,” said The Daily Star.
