People absolutely loved Calum Best's reaction to seeing his mum Angie Best entering the Celebrity Big Brother house.
Calum was the thirteenth housemate to enter the house and was rushed away to become one of the show's "producers."
The TV personality joins Spencer and Heidi Pratt, Austin Armacast, Jasmine Waltz, Nicola McLean, Coleen Nolan and James Jordan to chose which new housemate will be cut from the show.
However, when Angie entered the house, Calum's jaw dropped to the floor - and everyone else was as shocked as him.
Viewers took to Twitter about the hilarious reaction and many felt a lot of pity for the reality star.
