Jake Cornish and Liberty Poole - Jiberty - may have become the first official couple on this year's Love Island but viewers think there could be trouble in paradise.

On the eve of Casa Amor, viewers took to Twitter to reveal the tell-tale signs they spotted that show Jake, 24, isn't as into his girlfriend as he wants you to believe.

As cameras showed the boys and girls getting ready for bed, Liberty, 21, can be seen beaming as the girls call her "literally" girlfriend.

But in the bedroom, as Teddy Soares, 26, jokes that the water engineer is now a "w***er" since he's become coupled up.

And a stuttering Jake replies: "You know what? You're just jealous that you don't have a girlfriend."

But it's the way the hunk put his words across that had alarm bells ringing for the show's fans.

"Did u see how this mf Jake stuttered. He don’t like Lib #loveIsland," one wrote on Twitter.

Another seemingly agreed and commented: "jake is giving me massive red flags why aren’t you excited about having a girlfriend mate #loveisland"

A third said: "Jake definitely does not like Liberty. It’s giving actor. He will definitely dump her if his head gets turned in casa amor #loveIsland."

And even former islander Sharon Gaffka has suggested Jake could have a change of heart.

Speaking ahead of Casa Amor's return, Sharon said: "I think Lib is going to stay loyal, but Jake’s head could be turned. I could be proved wrong and I want to be proved wrong."

It comes as a Casa Amor newbie revealed she has her eyes firmly set on the Weston-super-Mare native and is about to try to turn his head.

In a preview, Lillie Haynes, 22, has revealed that she is very interested in getting to know Jake when the boys head to Casa Amor imminently.

The South Shields lass said: "I’ve definitely got my eye on Jake.

"He’s 100% the type of boy I would go for at home. It’s too good of a match not to just go for."

Last week saw Jake and Liberty officially become boyfriend and girlfriend as the islanders carried out a sweet dinner date for the pair.

It ended in Jake popping the question and giving the Brummy girl a magnetic bracelet which matched one he will now be wearing too.
