16-year-old darts star Luke Littler’s mother released his birth certificate to prove his age

Second-place PDC World Darts Championship finisher Luke Littler certainly doesn’t look 16, so his mom released his birth certificate to prove he was born in 2007.

Luke Littler took the sports world by storm this week as he advanced his way to the PDC World Darts Championship final. Everyone loves an underdog story; this one involved a 16-year-old competing against and beating some of the greatest dart players in the world in the most prestigious darts competition before falling to No. 1-ranked Luke Humphries.

Monikered Luke “the Nuke,” Littler became the youngest player to ever win a match at the tournament, according to ESPN. He led Humphries 4-2, but the top-ranked player won five straight sets to get the title.

Littler has been increasingly recognized when he ventures outside, with fans stopping him at the Arsenal game and Tottenham Spurs player James Maddison posing for a picture and bringing a sign to the championship.

But beyond that, the real reason Littler has grabbed the attention of so many is that, for a 16-year-old, he arguably does not look 16.

In this photo, taken five years ago, he was 11:

People on social media were making jokes about how old he looks, which he says have been “going on for years,” and he now “laughs off” the jokes, according to Daily Mail. But it went so far that his mother released a picture of his birth certificate to prove once and for all that this teenager was, in fact, born in the year 2007.
