The pair, who enjoyed a secret snog on Friday night, clash in this evening's latest highlights show.
It followed rows in Sunday night's show when Ellie revealed all to the other housemates about their kiss.
In tonight's episode, in the diary room, Sam is talking about Ellie: “We’re just having a laugh, a flirty banter, flanter! She seems a lot more happy since I’ve been in here. I’ll kiss her a few more times…”
Meanwhile, Ellie reveals to Simone about Sam: “I think he’s lovely…I’m not ready to settle down…I do genuinely like the guy.”
Later on, Sam asks Ellie to chat to him in the bathroom.
Ellie tells him: “All you do is follow Isabelle around! I’d rather just be friends…”
Sam replies: “I get on with her! For f**ks sake…I’ve not done anything wrong. I don’t fancy her, I fancy you.”
Ellie thinks: “It’s better to leave it as friends.”
Sam states: “I genuinely like you…”
The latest relationship drama between the pair follows Sam confiding in Ellie he felt like a 'substitute Lotan' for her yesterday.
"I feel like I've took someone's position, I feel weird. I'm Sam, I'm not anyone else. I've come in here to do my own thing, not to play someone," he said.
Big Brother 2017 continues tonight at 10PM on Channel 5.
