WATCH: Fans slam UK Big Brother's 'sex romp'

Everyone knows there's a distinct lack of privacy in the Big Brother house, but that didn't seem to bother two contestants on the UK celebrity series.

Fans flocked to social media over the weekend to slam contestant and former Girls Aloud member Sarah Harding after she was caught getting hot and heavy with housemate Chad Johnson. Check out the clip above.

Chad and Sarah took their CBB relationship to the next level, sharing a bed together and the house cameras capturing the intimate moment.

An insider confirmed to The Sun that the pair were intimate, but "producers had to carefully edit the scenes" to make sure they were suitable broadcast and nothing too graphic was shown!

"There's a lot of heavy petting going down between the couple," the source told the outlet.

"Sarah's hand disappeared under the covers and Chad's boxers came off. Viewers can draw their own conclusions about what happens but it's pretty clear."

Having been nominated by the entire house, except for Chad, Sarah has had her own drama-filled experience in the Celebrity Big Brother house, however fans were quick to take to social media to slam the model for her actions, calling her out on supposed "slut-shaming" comments she made about girl band members.

"Sarah is sly. hypocrite. A cheat. and attention seeker. get her OUT. her thing with chad wont last. She'll probs cheat on himm," one viewer tweeter while another added, "Sarah s**t shamed a girlband for what they wear but she's having sexual contact and cheating on her bf on national TV."
