The married couple and former stars of The Hills are to get "close protection" as part of a "huge security operation", according to the Daily Star.
The spouses - nicknamed 'Speidi' - have become figures of hate amongst Celebrity Big Brother fans after repeatedly talking behind their other housemates' backs, refusing to participate in tasks and, in the eyes of some, receiving preferential treatment from producers.
The backlash against them apparently intensified when they clapped during the news that Claire Richards would not receive a letter from home as part of a task.
One Twitter user wrote: "I want to kill Speidi the heartless cold creatures, they shouldnt be aloud to walk this earth, disgusting, should be ashamed of yourselves!!"
A member of the Celebrity Big Brother team commented: "Initially everyone seemed to love their meddling. But now it's turned into real hatred."
Former housemate Lacey Banghard declared in a post-eviction interview that she wants to "knock... out" Heidi after discovering she called Banghard a "wh*re" while in the house.
Speaking to Digital Spy yesterday (January 22), Banghard elaborated: "I thought they were really good people and honest people, and looking back at footage I can see that they wasn't. It just sort of disheartened me a bit.
"I'd like to use Big Brother in a good way, sort of try and help out other people, so hopefully they'll do the same."
Celebrity Big Brother continues tonight (January 23) with a live eviction at 9pm on Channel 5.
