Kinga was evicted via the backdoor with no eviction interview while Belfast model Orlaith and engineer Eugene got to enter the house and become housemates.
On hearing the news, Eugene said: "I'm quite shocked but really chuffed". Orlaith thanked Makosi, saying "You did so well".
Makosi then had to introduce her new housemates to the rest of the group. Unsurprisingly, Orlaith made an impression with the male housemates, with Anthony making a bee-line for her while Maxwell cracked open some champagne.
Makosi was selected by 'Big Brother' to go on the secret mission on after pressing a red button installed in the house last week with instructions to "Do not press".
The Zimbabwean nurse was told she had to feed and clothe the secret housemates for three days and keep their identity a secret from the other housemates.
On completing her mission, which culminated with the eviction of market researcher Kinga, Makosi will be immune from this week's eviction.
The two new housemates will also be exempt from this week's nominations.
