remember them? The American Backstreet Boys seem almost unrecognizable in Perth

American boy band The Backstreet Boys landed in Australia ahead of their tour.

Nick Carter, AJ McClain and Brian Littrell were spotted having dinner at a hotel in Perth on Thursday.

The trio looked almost unrecognizable as they grabbed a bite to eat and puffed cigarettes away from the lights before their series of shows, which begin Saturday at the RAC Arena.

The Backstreet Boys, consisting of Nick, AJ, Brian, Howie Dorough, and Kevin Richardson, are the biggest selling boy band of all time and have sold a whopping 100 million albums.

They are due to play in Perth on Saturday, before heading to Melbourne, Sydney and Queensland as part of their DNA World Tour.
