In an interview with The Sun today, Angie Best spoke about a recent incident on CBB in which viewers saw Perez screaming at Calum: "I will be the huge d**k and I will shove it up your a**e."
Perez was given a warning by Big Brother for his behaviour.
Talking about it today, Calum's mum Angie said: "My first feeling was I was disgusted, but the poor boy is madly in love with Calum.
"It's not real life on the show, he's shouting his mouth off. I just can't take Perez seriously at all."
Calum has emerged as a fan favourite during the current series of CBB thanks to his laid back attitude and reluctance to become embroiled in any drama.
He's spoken openly in the house about the death of his father, late footballer George Best, and how proud he is to carry on the family name.
Angie told The Sun that she'd feared Calum would become lost to alcohol as his father had, but she was "so proud" of Calum being able to pull through his dark days and get on with his life.
"It was a dreadful time and I'm so proud of him for having the strength of character to walk away from the situation a better man."
