While sex mongoose Charlie popped out for a bit, it turns out that Big Bro twins Sam and Amanda were aching to get into some girl on girl action - with each other!
An anonymous source said, "They'd love to snog each other off. Seany would love to watch but he bats for the other side. So that leaves Ronseal faced Ziggy to get himself covered in stardust as the two blondes get steamy for him."
Commentators have hinted that wasp-tempered Charlie wouldn't stand for any of Sam and Mandy's shenanigans. One friend of the show gasped, "There's no way Charlie would sit on her thumbs while all that was going on. She'd whip 'em off and get stuck right in - and get Brian to get oiled up and strip to his undies."
C4 think the twins will make a 'phwoarterfall' by pouring watering cans full of icey cold water down their bikini tops, then pulling the heads off all the flowers in the BB garden with their bums in the air.
And C4 hope viewers will get a ratings boost while viewers do the same, watching the teen sex sensations!
