Westlife singers SHANE FILAN and NICKY BYRNE were amazed when Brian McFadden quit the boyband, because he was throwing away his financial security.
MCFadden left the Irish group to go solo in 2004, but his subsequent releases have failed to match the success of Westlife.
Filan says, "It was his decision to leave the band and we respect that 100 per cent, but... you'd be mad to leave Westlife, purely on a financial basis.
"But if you're not happy in your personal life, then money doesn't matter."
Byrne adds, "When you see how happy we are, you do feel, `Jesus, why would you want to leave that?'
"We live amazing f**king lives, we see the world over, we perform constantly."
