Jay Leno has been handed a certificate after completing the Fatburger XXX challenge.
Jay Leno devoured a 24oz burger in just five minutes to be crowned the latest Fatburger XXX challenge champion.
The 64-year-old talk-show host has gone some way to furhter his status as a big mouth by chowing down on the three-patty calorific treat at the new Beverly Hills Fatburger branch, TMZ reports.
The monster meaty meal may not have done Jay's waistline any favours, but it was enough to earn him a certificate and secure a place in the Fatburger unofficial hall of fame.
Another high-profile customer at Fatburger is US boxing champ floyd mayweather, who was snapped devouring some fat-filled grub in the Nevada version of the restaurant earlier in the year.
However, both stars still lag some way behind one former customer who managed to consume a 16-patty, 128oz burger in 35 minutes.
It seems that meat-eating challenges are popular in the celebrity community at the moment, as Joe Thomas and Blake Harrison - who play the roles of Simon and Neil in 'The Inbetweeners 2' movie - revealed at the premiere of their new film that they did something similar on their jaunt to Australia.
The boys filmed much of the new movie Down Under, and revealed they took some time out in between filming to take on a similar challenge - but were significantly less successful.
Blake, 29, told BANG Showbiz: ''Me and Joe did a meat-eating challenge where we were quite sick afterwards.''
Joe added: ''It was a horrible experience in every way, in every bodily way it was horrible. But mentally it was very nourishing.''
