As part of the ongoing prize fund task, Sam and Ellie are called to the diary room.
They are invited to spend the night together in the spare bedroom following Chanelle's stay with her boyfriend. They accept and £400 is deducted from their teams’ money pot.
Meanwhile, on the sofas, Chanelle reveals about her night with her boyfriend: “We tried to go under the covers…it was like married couple sex…it didn’t last long!”
In the private room ahead of their night together, Ellie and Sam get a chance to talk away from the rest of their fellow housemates.
Ellie tells him; “Let’s pretend it’s our first date…we’ve got to know each other in such a short amount of time.”
Sam reveals to her; “I do genuinely like you…I wasn’t expecting this.”
Ellie confirms she likes him too and adds; “For now let’s keep a guard up. I’m scared, I don’t want sh*t to happen again.”
In the main house, in the diary room, Charlotte is talking to Big Brother about Sam and Ellie; “When he first came in I thought he was desperate for fame, he’s just young and dumb.
"Neither of them are too bright! I think Ellie definitely likes him more than she thinks she likes him. It’s honeymoon stage!”
And Deborah and Hannah believe Sam ‘wants to be a reality star’
Back in the bedroom, Sam and Ellie are getting closer and kissing in bed.
Sam tells her; “I quite like you. I didn’t plan to like someone, I was expecting it.” Ellie adds; “Just me and you.”
The pair then go to sleep together.
Big Brother 2017 airs tonight at 10PM on Channel 5.
