Singer reveals Louis Walsh slapped him in the FACE

Shane Filan’s autobiography My Side of Life is revealing a LOT of juicy celeb secrets – like that time he got slapped in the face by Louis Walsh!

Shane and the rest of the Westlife lads were auditioning for Simon Cowell but Shane had been out the night before with then-girlfriend (now his wife) Gillian and was feeling a little worse for wear.

After a rather disastrous rendition of a Backstreet Boys’ song, Louis stormed up to Shane, slapped him and said: “What the fu** was that, Shane?! … It was sh**! He didn’t like you!”

It would appear that unlike Louis, Simon didn’t think Shane looked, acted or sang like a pop star…but Louis solved all of that.

Dying his hair blonde, Shane went for another audition, this time impressing the music mogul and signing Westlife to Syco.
