The Sugababes appearance comes after the original trio are said to have been left furious as former members plan rival concerts using the group's name.

Heidi Range, 40, who was member of the band between 2001 and 2011, is said to be in talks to hit the road with Amelle Berrabah, 39, who was also in the line up between 2005 and 2011.

A source told The Sun: 'Heidi and Amelle have been approached about doing a tour as alternative Sugababes and their first call would be fellow ex-member Jade Ewen.

'There's a huge appetite for the Noughties and Heidi and Amelle can offer fans something very different to the original line-up'.

'The original trio are furious that the others want to try and use the name as they feel it's theirs.'

MailOnline have contacted Heidi and Amelle and Sugababes' reps for comments.

Sugababes shot into the charts back in 2000 with their debut single Overload and went on to enjoy a plethora of hits including About You Now, Freak Like Me and Push The Button.

But it wasn't always plain sailing and the group were renowned for their fall outs which led to the line up changed three times before returning to the original threesome in 2012.

Siobhan left in 2001 and was replaced by Heidi, Mutya left in 2005 and was replaced by Amelle and Keisha was replaced by Jade when she departed in 2009.

The replacement members stopped making music in 2011.

The band reformed in 2012 with their original line-up, under the name of Mutya Keisha Siobhan as Sugababes was still owned by their previous record label, they won back the rights to the name in 2019.
