In a new video shared by Channel 5, the pair can be seen kissing while in bed together, as well as hiding under the duvet to keep out of the way of cameras.
Although, Megan did seem to give the game away, telling her housemate: "You're so naughty Scott."
Since entering the CBB house together, Megan and Scott have kept viewers entertained with their flirty antics and have been spotted snogging on several occasions.
Despite locking lips with Scotty, Megan had insisted the pair were just friends, but she did confess to Stephanie Davis that she "really fancies" the Geordie Shore star.
It had seemed Megan had blown her chances with Scott, after recently confessing she had got her own back on a cheating ex-boyfriend by hooking up with his friend instead.
Scott criticised her for doing so, telling Megan: "I hate things like that, it annoys me. Even if my ex-bird had cheated on me a thousand times, I would still never break up a friendship with her, just because I wouldn't want to lower myself to that level. That's the worst thing."
However, it wasn't enough to put him off Megan completely and he later hinted at a continuing romance between the pair.
Megs had asked him if he was completely single and gesturing towards her, the reality star teased: "Clearly not."
Megan's flirting with Scotty comes after her ex-beau Jordan Davies recently claimed his Ex On The Beach co-star Scott had done him a favour.
After seeing Megan's outburst on CBB (where she received a formal warning over her foul-mouthed tirade at John), Jordan told The Sun: "He's done me a favour because she's not the girl I thought she was... Megan is Scotty's problem now, not mine. Good luck, Scotty – that's all I'm saying."
Scott's ex, Ashleigh Defty, meanwhile, has hit out at his romance with Megan, insisting it is all for the cameras.
She said: "Seeing Scotty and Megan together doesn't bother us in the slightest, and I'm certain that nothing will happen when CBB is over - it's definitely a showmance."
