Smith, meanwhile, found himself defending the use of pop star Williams' song, after the singers well documented struggles with cocaine addiction.

"These events you've got to keep in perspective. Every single day of our lives things happen and you've got to deal with those things."
The NRL season gets underway next Thursday with the Brisbane Broncos hosting reigning premiers, South Sydney, at Suncorp Stadium in Brisbane.
