The Manchester lass has already shocked fans of the Channel 5 show after after flashing her knickers as she arrived in a racy gown and yelled “f***y flaps” at host Emma Willis.
But her latest revelation about her boyfriend’s penis was a step too far for many people watching at home.
Talking about her beau, the 24-year-old admitted: “I’ve only been with him for six months but he’s dead supportive, I can’t find a man who likes me for me.
“And he’s got a 10 inch d**k so it’s not bad. He’s a very giving person.”

Fellow housemate Kayleigh Morris didn’t appear too stunned by her comments and replied: “I don’t like giving b**w j**s.”
“I’ve not got the patience to do it until they c*m,” Chanelle responded.
Big Brother viewers couldn’t believe what they were hearing and flocked to Twitter to share their disgust over the conversation.
One person wrote: “Since when is talking about giving b**wj**s a normal thing to talk about when you've just met? #BBUK [sic].”
“I think I must be getting old. Some of the stuff coming out of #bbchanelle's mouth is a bit too for me. #bbuk #bigbrother,” commented another viewer.
