Heidi Montag and Spencer Pratt Don't Fall for 'Borat' Creator Sacha Baron Cohen's Latest Prank

"The email from Sacha Baron Cohen tryna get Speidi," Pratt tweeted Monday afternoon, along with a picture of a reality TV pitch for a project tentatively titled "Security Makeover," which would allegedly air on "the Israeli network."

"Our show is focused on common safety concerns that people experience in the 21st century and we have an Israeli security expert who'd like to advise a couple on safety tips in hopes that our audience can learn from their experience," the email read. "We believe our international audience would like to learn important safety tips via a fun, informative interaction with a dynamic and glamorous couple like Heidi and Spencer."

"We have rented a home in Orange Country and would like to film with them for 1-2 hours this Wednesday 1/31. We could pay them a fee for their on-camera appearance and they'd also be able to promote any products/books or anything else they'd like to promote," the pitch continued. "We'd also send a car service and provide hair and make up. Please let me know their level of interest. We'd love to have them participate."

While the "The Hills" stars, who are married with a kid, say they didn't fall for the prank, former "Real Housewives of Orange County" star Gretchen Rossi and Slade Smiley sure did. The reality TV couple told Page Six they accepted the offer because they thought it would be a good opportunity to learn a protocol in the event that they had a break in. But much to their surprise, they got a much more hands-on experience than they were anticipating.

"The second we walk through the door there's two Mossad agents holding guns to each other's heads," Rossi said. "They punked us for four-and-a-half hours! You would not believe the stuff they were asking us to do -- the weirdest, creepiest, funniest stuff, but at the time it wasn't funny. We literally thought they were going to kill Slade!"

"I was freaked out. I was crying," Rossi added. "I was hysterical coming home. I'm sure they were laughing their asses off."

The couple continued to explain that they had no idea the crazy man instructing the entire event was Cohen in disguise, but later tried to call the production company to ask about what went down, but "everyone went dark."

"For two days we had no idea that this had really happened," Smiley said. "We went to a magazine photoshoot and Tito Ortiz was on the shoot and we were talking about things and he was like, 'F-ck dude, I think I was punked by Sacha Cohen.' I go, 'What do you mean?'... And he started describing exactly what happened to us."

"He needs to win an Oscar for his performance," Rossi added. "Incredible."
