The news was 'unveiled' on Twitter by the 'girls' in the following manner: "We are SO excited to be performing on the main stage at @PrideBrighton on August 3rd!! Can't wait to see some of you there x #brightonpride."
Perhaps this means a song will be out around that time too, but who knows.
This is all very well, but what does Pride's Programming director Dulcie Danger think about it all?
"MKS will be performing some new material as well as some of the Sugababes' biggest hits live on our fabulous main stage," he said (as quoted here).
"I can't tell you how excited we are about it, they are truly an iconic pop act and are going to make a huge impact on the day."
