But what Adam hadn't banked on was that Megan would come straight to Rosie and tell her the truth, and Rosie was definitely not taking the slight lying down.
They think it's to do with the dramatic showdown between Rosie and Adam which dominated last night's episode.
She also broke down in tears to the women, saying she just wanted to be enough for a man.
Following the announcement his partner in the villa, Georgia Steel, said: 'Obviously I was coupled up with him so obviously I came closer to him than most people in here but it wasn't just that.
Niall originally paired up with Kendall in the opening week, but she was stolen from him by Adam.
On her official Twitter page, she tweeted: "Go on Laura!"
She wants to know exactly how Adam feels about Rosie. which is when he drops a bombshell! We got on really, really well.
"I just want you to realise, with Kendall as well as Rosie now, they are both really good girls", she began.
Will Rosie choose Adam at the recoupling?
She told him: "You say about Niall not being honest the other night, but you literally did what he did. and didn't have the balls to tell me before that you were going to do it". "It's fine if you decide then that you don't like Rosie, you don't have to like everyone but it's just these girls have feelings as well and the way that you've acted is just stupid and you don't need to be like that".
Pulling him up on his previous comments, she added: "You don't want to be with someone who is insecure, you've already said that, but your actions are making girls insecure".
The tweet comes after it was rumoured that Amber's ex Kem Cetinay is getting cosy with Kendall Rae-Knight, who was the first star to be kicked out of the villa this year.
