Love Island ended on a dramatic cliffhanger last night when Adam Collard's shocking secret was exposed.

Viewers suffered a restless night trying to work out what the naughty lad had done to upset Rosie Williams .

The Welsh solicitor was left in tears after discovering something nasty about the Geordie that leads to a full-blown showdown in the villa.

Adam has already cemented himself as the villa villain after snogging Rosie just minutes after dumping Kendall Rae-Knight in 'disgusting' lack of respect

So what has Adam done this time? Here are all the theories?

Cheated with Megan

Adam has form for ditching his partner for having his head turned by a new girl.

The personal trainer was settled with Kendall, but he couldn't resist cracking on with a sexy new singleton.

Unable to see a way forward, Adam claimed he wanted to "nip it in the bud" and said they'd be better as friends.

With his conscience cleared, the dirty dog decided to pursue things with Rosie straight away and took just four minutes to lock lips with her.

It's also been established that Adam likes kissing on a first date - and so does Megan.

Has he been flirting with the model? And did they share a kiss?

Sending secret flirty texts

Adam also has a history of sending flirty texts.

Islanders' phones aren't just for getting texts from the show's producers - they can use them to take photos and communicate in secret.

After dumping Kendall, he started texting Rosie from his makeshift bed on the sofa.

"Plenty of room," he messaged his new beau.

She replied: "Lonely are we?"

He's the sort of guy that wants a late night booty call asks if you're up at 3am.

Has Adam been getting up to no good on his phone?

Dani is involved

In the teaser all the other Islanders gather around, Rosie confronts a sheepish Adam.

"Do you want to tell me something?" the fuming solicitor asks. "Something that happened today that you should have perhaps had the balls to tell me before.

He grins and asks: "What you on about?"

Trying to keep calm, she says: "I dunno, what am I on about? Everyone else in the group knows about it, you may as well share it. The group's waiting."

It seems some of the Islanders know the secret and Danny Dyer's daughter puts her hand up to stop Jack talking.

Does Dani Dyer know more than she's letting on?

Adam already knows Rosie

Eagle-eyed viewers spotted seemingly incriminating photos of them with an identical designer bag on Instagram (

Love Island fans think Adam Collard and Rosie Williams knew each other before coupling up in the villa.

Eagle-eyed viewers spotted seemingly incriminating photos that could prove that they have met before taking part in the ITV2 dating show.

Adam and Rosie were both pictured with identical designer bags in separate snaps posted on their Instagram pages.

Concerned Love Island viewers believe this may prove they met up before.

Could something from the outside sparked the argument?

Kendall is back

Kendall was Adam's first love in the villa - and you never forget your first.

The pair did have a connection but he was put off by her insecurities (and the fact she wouldn't kiss him again).

He decided to couple up with Rosie and sent Kendall packing, but she still holds a torch for him.

After leaving Kendall confessed that she didn't want to be fake and move on to someone else when she still fancied Adam.

She's also admitted she would return to the villa if the opportunity arose to be with someone she fancies.

Could Kendall be coming back?

Adam is lying about his background

Is he really 22? (

Love Island viewers were shocked on the first night when Adam revealed he was 22-years-old.

Some fans were convinced he was much older due to his ruggish looks.

They even speculated that Adam might have kids at home.
