Love Island fans have slated islander Callum Jones after tonight's explosive episode.

Both of the villa's residents took part in a series of challenges which ultimately led to the newcomers of Casa Amor locking lips with the boys, and the girls smooching up to the new boys in the original digs.

In one particular challenge, Callum, who is the tallest boy, was asked to 'snog' the girl he fancies the most for five seconds.

Have we just witnessed the end of Callum and Shaughna ?

Without even taking a breath, the 23-year-old shot to his feet with a look of pure ecstasy on his face, knowing full well who he was going to lunge for.

Shaughna's other-half threw himself upon the blonde bombshell's lips, and fans of the show rushed to Twitter to share their thoughts on the 'cringe moment'.

Callum couldn't contain his excitement at the prospect of kissing Molly

"Callum literally lunging himself on top of the poor girl. He needs to be deleted!" wrote one unimpressed viewer.

"He nearly got bloody whiplash he jumped up so fast, Jesus!" quipped another.

While a third tweeted: "The state of Callum. He almost fell over himself to try and snog that Molly Mae knokck off!".

The pair have been sharing a bed

Despite his 'muggy' mannerisms in tonight's episode, Shaughna wasn't an angel either.

The blonde beauty found herself spooning on the day bed with newcomer Biggs in the challenge due to the fact the pair had the most tattoos.

The 25-year-old also ended up kissing George's naked torso twenty times as part of the raunchy challenge.

While many fans understood that she was obliged to take part in the sexy scenarios, others slated Shaughna for constantly 'winging' about Callum cheating on her, when she's doing 'the exact same'.

"She needs to put an end to this winging and get over herself" wrote one fuming fan.

While another quipped: "LOL she's doing the exact same as Callum. But of course, double standards for a dumb bi**h!.

With all that being said, things aren't looking too promising for poor Callum and Shau!
