Westlife and Louis Walsh were a match made in heaven - but it hasn't always been smooth sailing.
The former X Factor judge first hit the big time when he decided to create an Irish version of Take That by holding open auditions for singers, which resulted in the formation of Boyzone.
After many successful years together and working with Ronan Keating as a solo artist, Louis, who turns 70 today, went back to the boyband formula with new band Westlife.
