Boy band legends New Kids On The Block and the Backstreet Boys have formed the ultimate boy band supergroup.

The collaborative project, now known as NKOTBSB, will feature the first recorded songs from the combined act, including their first single ‘Don’t Turn Out The Lights’. The album will also feature classic hits by both groups and is due out in October in the UK after being released in the US earlier this year.

With over 200 million albums sold between both bands and between hits like 'I Want It That Way' and 'Hanging Tough', both groups have dominated the pop world for over three decades. With that, NKOTBSB are also set to tour the UK this October.
