After the interview Kiss Daniel granted to Punch which suggested that he was lying about his age. there have been a lot of theories about his actual age
A screenshot of his Wikipedia page has surfaced online which allegedly suggest that he just changed his age.

The screenshot of his Wikipedia page showed his birthday as 1 May 1994 which makes him 21 years old but after editing the page, it now shows his birthday as 1 May 1984 making him 28 years old.

The page shows that it was edited few hours ago

See screenshot below

I however checked his Wikipedia page now and it shows 1 May 1994 (21 years) as his birthday.
