The four piece are set to join American 90s boy band The Backstreet Boys on a UK tour next year.
Made up of sisters Nicole and Natalie Appleton along with Shazney Lewis and Melanie Blatt, the girl group sold over 10 million records, making them one of the best selling girl groups of all time.
The band said:‘We are really looking forward to performing together as special guests of the Backstreet Boys.’
They continued: ‘The Backstreet Boys are a great band, so it's an honour. We're singing a lot of big songs like Never Ever and Pure Shores, which will be amazing. We can't wait!’

The band is reportedly not releasing any new material any time soon but instead will focus on performing their 90s hits.
All Saints formed in 1993 and released songs such as ‘Under the bridge’ and ‘I know where it's at.’ They won 2 Brit awards as well as an Ivor Novella award for their single ‘Pure Shores.’ The single also featured in 2000 Leonardo di Caprio movie, ‘The Beach.’
They split in 2001, but reformed in 2006 to record a new album. Their new material, however, failed to match their previous success.
All Saints member Nicole Appleton has been in the headlines recently due to her troubled marriage with Liam Gallagher. The couple are reportedly set to divorce after it was revealed that Liam had fathered a love child with American journalist Liza Ghorbani.

This year has seen several pop bands from yester-year reform. TV show The Big Reunion traced the preprations of a massive reunion tour featuring B*Witched, Blue, 5ive and Atomic Kitten.
