While Leap Day might not hold huge significance for most of us, it's a crucial day for anyone born on February 29, who technically only has a birthday once every four years.

People born on February 29 have to decide whether to celebrate their birthday on February 28 or March 1 - although it's a often joked that Leap Day babies are technically a quarter of their own age. 

It's not unheard off for celebrities to shave a few years off their age in order to appear younger, but Leap Year babies can jokingly claim they're doing this legitimately. 

So who are the famous faces born on February 29 and what are their Leap Year ages versus the real number of years they've been on this planet?

The rap artist Ja Rule, real name Jeffrey Atkins, turns 48 today - but his Leap Year age would be 12.

Ja Rule 

American rapper Ja Rule was born on 29 February 1976. 

The rap artist, real name Jeffrey Atkins, turns 48 today - but his Leap Year age would be 12.

In 2016, Ja Rule cracked a joke about his age when he turned the 40 during the launch of his Las Vegas show, writing on Instagram at the time: 'My @foxtailatsls residency kick [sic] off crazy wit [sic] my 10th bday party lol.'

It comes after the rap icon revealed yesterday that he was denied entry to the United Kingdom because of his criminal record days before the start of his almost sold out tour.

It comes as Ilia Topuria has been promised a Spanish citizenship after meeting up with the nation's Prime Minister on Tuesday.

Earlier this month, the 27-year-old became the first Spanish champion in UFC history after his stunning KO victory over Alexander Volkanovski at UFC 298.
