It's the final night in the house for Marnie Simpson, Gemma Collins and Nicola McLean and the end of this week's shopping task.
Once the task is finished, the celebrity guests hold a party which begins with a girls vs boys dance off in the garden.
Later in the living area, Marnie tells Ellie how she likes to act sexy and shows Ellie how to do it.
Marnie says “It’s all about the nipple and it’s all about the mouth.”
Nicola asks Marnie if she can lick her own nipple and Marnie says “I try” and shows the group.
The housemates then play a game of truth or dare in the living area and Marnie and Ellie are given a dare to kiss each other.
After they kiss Ellie says “I finally got a kiss in the house”.
Next, Charlotte is given a dare to do a sexy pole dance on the lamp post in the living room.
Elsewhere tonight, Lotan impresses the girls with a strip tease and Marnie and Kieran share a kiss.
Marnie says: “It was the best kiss I’ve had all year.
"Better kiss than Lewis, 100%.”
Big Brother 2017 airs tonight at 9PM on Channel 5.
