Markus Feehily won't take part in 'I'm A Celebrity... Get Me Out Of Here!' because he's scared of birds.
The former Westlife star - who's old bandmate Kian Egan was King of the Jungle in 2013 - could think of nothing worse than being eaten alive by pests as the thought "terrifies" him.
He explained: "I've been asked to do all the main reality shows. The idea of being buried alive in a coffin with rats in the jungle absolutely terrifies me.
"I have a massive phobia of birds and remember seeing Johnny Rotten have bread attached to his entire body while two or three ostriches were attacking him in a pen."
The 35-year-old star is a fan of watching the show and despite being too frightened to go on it, he thinks it would make great viewing for people if he did.
He told the Daily Mirror newspaper: "It's fun to watch - but I would have a cardiac arrest. It probably would make great TV, seeing me screaming for my life."
And Markus was so proud of Kian for winning the reality show that he was jumping up and down and shouting at the TV in excitement.
He previously said: "I was literally screaming at the TV when Kian was in the jungle. I was literally doing back flips when he won."
