Worthington first made headlines over a decade ago when he threw a party at his parents' home which ended up with over 500 guests.
A police helicopter and the critical response team were called in to disperse the crowd after party-goers started damaging cars and properties on the street.
Following the interview, Corey made headlines worldwide. He added to his notoriety by refusing to take off his yellow sunglasses during interviews.
'It’s the ultimate Where Are They Now?' Fordham told news.com.au. 'This guy was there one minute and gone the next and I don’t think anyone has probably given too much thought to him in the meantime…But he has been doing something behind the scenes since then because he is buff!'
Corey also confirmed the news, taking to his Instagram account @partyboy_c_worthington.
Fordham, who co-hosts the hit show alongside Rebecca Maddern and Freddie Flintoff, further told news.com.au that Worthington applied to be on the show and got through the grueling audition process.
'We didn’t go looking for him. He watched Ninja Warrior last year like everyone else and it turns out he’s a fit little fella these days and he wanted to have a crack,' Fordham said.
Worthington, now 27, isn't the only famous face we'll be seeing on Season 2 of Ninja Warrior.
NRL star Paul Gallen and The Bachelor’s Tim Robards will also give the course a go.
