The pair were both evicted together on Friday night alongside Chanelle in a triple exit.
But despite having the weekend to themselves, the couple have yet to "seal the deal".
Speaking to Rylan Clark-Neal on last night's Bit On The Side, Ellie said: "No!
"He couldn't get excited. I banged my head and was nearly concussed because I was that excited about it.
"That's what happened.
"He's got one more chance tonight."
Sam confessed: "It is the truth."
He added to Rylan on the spin-off show: "You know when you go to bed and you think what's going on here - I had had a bit too much to drink.
"I'm not going to lie."
When the pair were chatting with Emma Willis after their evictions last week, both said they wanted to take things slow on the outside.
Sam said: “We are going to meet each other and go for food. We will see how it goes. It’s not often I like someone. She gets me and not many people get me.”
And talking about Sam to Emma, Ellie said: “I’d like to get to know him out of the house. It would be nice to go to a normal pub and have a normal drink.”
