Viewers have watched the former Hollyoaks actress grow close to Jeremy over the past two weeks, even sharing a kiss with him, despite dating Sam in the outside world.
It's led to plenty of speculation about how Sam is feeling.
However, one Twitter user last night voiced the suggestion that Sam and Stephanie could have planned everything ahead of entering the house...
The user had tweeted: "So was it planned by @SamReece and #cbbstephanie to do the act she is doing, or are they really not together but want some press #cbb @bbuk."
NO! Said Sam!
Responding to the tweet, he said: "I find it very disrespectful the fact you think I would set something like that up.. Come on love!!"
It's the first time Sam has referenced his relationship with Stephanie since 11 January when he withdrew his support from her via Twitter but insisted they remain a couple.
"Monday's comment was me withdrawing my support via social media for the time being. I will be talking to her when she leaves the Big Brother house," he had said.
"I would never end a relationship over text or social media. I want to talk to Steph face to face."
Meanwhile, the model has also denied he is the special guest that will enter CBB this week.
Stephanie is immune from the next eviction.
