Chad Johnson and Sarah Harding had sex in the Celebrity Big Brother toilet, it's been claimed.
Former housemates Paul Danan and Brandi Glanville made the shock accusations on last night's Bit On The Side.
Speaking on the spin-off show, Paul said of Sarah: "Lovely girl but she's really f**king that s**t up."
Brandi meanwhile slammed her "bulls**t" romance with Chad. It's co-dependency and it's disgusting, it's like the grossest thing I've ever seen in my entire f**king life."
Paul then went on to claim: "It's not love, it's definitely not Love. I think it's a load of bollocks to be honest. And Sarah getting laid in the toilet isn't a good look."
Brandi backed up Paul's claim, saying it "100%" happened.
Host Rylan Clark-Neal was quick to intervene and point out: "We can neither confirm nor deny that When Sarah comes out I will ask for her."
Paul then added of the couple: "They need to spend more time with the housemates rather than on top of each other.
"The Chad is amazing but I think he's getting a bit too p***sed off at the way Sarah speaks to him an I think he needs to do his own thing
Last night's highlights saw another turbulent time for Chad and Sarah.
At one point they got themselves into a HUGE argument.
"Listen to me, I've been in this business fifteen f**king years, you're just starting out," Sarah told him. "You're just starting out mate, don't f**king ake the p***."
"What is your drama?" a puzzled Chad asked. "What did I do so bad. Why are you mad at me?"
However the couple quickly made up and spent the evening getting cosy in bed.
"I do love you," Chad told Sarah, "As a person for sure. Am I in love? I'm not sure yet but I do love you."
"It takes time you've gotta get out of here," Sarah replied.
"I know I love you, though. Because I just know I do," Chad insisted. "I do love you."
The couple then got frisky with Sarah telling Chad: "You're like a naughty kid. Just wait till Friday."
