The boys were away getting themselves pampered and lounging by the pool while the girls had an unexpected arrival.

To say that the girls were excited for a new boy to enter the villa is a bit of an understatement. After they sat themselves down, and took a moment for Paige to read out her text, they found out that a boy called Adam was about to enter the 'Love Island' villa. Little did they know that it was Adam Collard from season four.

In case you didn't know, Adam ("from season whatever") is the OG villain, the number one manipulator of the match-making show; he has gone down in history as being one of the most untrustworthy boys to take part in the competition.

And it seems the boy hasn't learned all that much in the past four years, as he's undoubtedly entered the villa to ruffle a few feathers.

On last night's episode after his big arrival, Adam pulled Paige, Tasha, Danica, Ekin-Su and Gemma for chats. He really quizzed them on their openness within their couples, while also off-handedly planting some seeds of doubt about whether they're with the boy of their dreams.

When it came to Adam and Gemma's chat, it began to wind down at the perfect time as Luca ("oh") and the boys returned to the villa to meet the returning contestant. Judging by the tease for tonight's episode, Jacques is not one bit happy. We guess karma is a bitch, eh?

Here are some of the best reactions from viewers last night as Adam Collard turned the 'Love Island' formula on its head.

'Love Island' continues tonight on Virgin Media Two and Virgin Media Player at 9 pm.
