London, July 22 : Big Brother odd couple Bex Shiner and Luke Marsden set the TV screens on fire after a live all-night romp on the show.
The couple dived beneath the covers and the cameras caught the duvet moving up and down.
Microphones near the bed picked up some bizarre moaning and grunting, and after they had finished a scruffy Bex came out of the covers to straighten her top.
However, the reality show's bosses refused to confirm the romp, which has triggered a buzz.
"You will have to ask them what they did when they leave the show," Daily Star quoted a spokeswoman as saying.
Luke had once said, "I don't fancy Bex. She smokes, she drinks, she swears. She is everything I hate.
"If you offered me 100,000 pounds or Rebecca, I'd take the money. She is bonkers."
