First to heat things up are Kayleigh Morris and Tom Barber who strip down to their swimwear and lather up together in the bathroom.
A sneak peek from tonight’s episode, which was posted on the Big Brother Twitter account, shows the pair washing each other as the shower door steams up.
Tom’s tattooed arms can be clearly seen as he pushes his face against the glass with his eyes closed.
Kayleigh meanwhile is stood behind him in a printed bikini and appears to be rubbing his back in the ridiculously racy scene.

The snap was posted alongside the caption: “10.33am: 1. Kayleigh & Tom are sharing a shower. 2. WTF?”
But they aren’t the only ones to enjoy their morning shower as Arthur Fulford left his female housemates flustered when he went completely naked.
The girls could be heard commenting on his penis as he flaunted his figure in the shower, choosing to ditch his swimwear.
“I can see it from here, it’s dangling right down,” one housemate could be heard noting.
