Love Island viewers are demanding to see newcomer Liam's passport to verify his age.
Following the dramatic departure of Shannon Singh, the sun soaked villa was looking a little empty until fans were introduced to two new islanders.
Newcomers Liam Reardon and Chuggs Wallis caused quite a stir when they entered the villa during Thursday night's episode.

But it was Liam's age that had fans going wild on Twitter..
Before the episode, the public voted for which lass they wanted to see spend time with each of the newbies over a candlelit dinner.
Fans decided that Faye Winter would go with Liam and Sharon Gaffka with 23 year old Chuggs.
Some viewers were not impressed with these couplings as it seemed as both Faye and Sharon were starting to settle down.
Sharon had agreed to see where things would go with model Aaron Francis whereas Faye was considering if PE teacher Hugo Hammond was her type on paper.
But despite this viewers were even more shocked when they learned during the date that Liam, who is a bricklayer from Wales, is only 21 years old.
Meaning he was born in 1999.
@KatieWillxo said: "If I drop my age range on Hinge are the boys gonna look like Liam?"
@johnsonlouise_ added: "Liam is this years version of Finley, no one believing his actual age of 21"
@Vee_raee commented: "How is Liam 21, is he counting his age is dog years?"
@mervn25 agreed and said: "Liam looks like dad of three but is my age mate??"
Faye, who is a 26 year old lettings manager from Devon, appeared to be thrown back by Liam's age before revealing she has dated younger lads before.
