So they got the shock of their lives when host Emma Willis revealed that they weren't actually being evicted.
In a classic CBB twist, Jenna and Farrah are now living in luxury in a secret suite where they can spy on the rest of the housemates!
Farrah was the first to be 'evicted' on Friday (11 September) and came out to quite a substantial amount of booing.
And when Emma filled her in on the plans for her to move into the top secret hideaway, the Teen Mum star didn't seem too pleased. In fact, she announced: "I'm running away!"
Jenna, who was fake evicted second, was more keen on the plans and shouted: "Oh my God, Emma!"
The pair were then reunited in the diary room, given immunity from next week's nominations AND told that they could chose who will be up for the chop next.
But of course the twists don't end there. Little do the girls know that the housemates will be filled in on their secret hideout and whoever they put up for eviction will actually gain immunity. Oh sneaky!
Farrah and Jenna have struck up quite the friendship on the hit Channel 5 show of late, and have even come up with a natty nickname for themselves.
Are you pleased that the girls have stayed on the show? Tell us below!
