Former Boyzone star Keith Duffy warns reality stars of the risks of overnight fame

The 47-year-old singer singled out Love Island stars who set themselves up to suffer from mental health issues because of their easy ride to fame.

As a result, Keith says they have "no defence" against trolls.

"To become famous for being famous, for me it's terrible,” he told the Andy Jaye podcast.

"You can’t get there just by one leap... you’ve got no defence and you’ve got no depth of character.

"If you really want to be famous go to college, go to art college, busk on the side of the road."

Keith admitted it was "difficult" in the 90s when Boyzone first shot to fame, due to their huge success.

The former Corrie actor told how he was "always pushed to the back" during the height of Boyzone's fame when he performed with Mikey Graham, Shane Lynch, Ronan Keating and Stephen Gately.

"It was really difficult in the 90s being in Boyzone because we were so successful,” he said, “but Shane, myself and Mikey probably would have been looked upon as not being there for our voices.

"It was difficult when my mum and dad came to see us playing Wembley – I wasn’t up front as I was pushed to the back.”

However, he said that now he "gets much more out of what he does" as he is the lead singer in duo Boyzlife, with Brian McFadden.

Speaking to OK! Magazine about their new single, which is set to be released in May, Keith said: "Brian had a solo career where he had No 1 songs all over the world that he wrote.

“ I didn't do a lot of the big hits that Boyzone had, so working with Brian now, I get much more out of what we do because I'm singing lead.

“I’m delighted I get to do what I do with Brian. My dad passed away last year, but he came to a few of our shows and he got to see me up front."
