This afternoon, the original Sugababes, made up of Mutya Buena, Siobhán Donaghy and Keisha Buchanan, shared their first post on Instagram, which is a teaser of their original logo with a piano melody over the top.

Sugababes captioned the post with a link to their site, which shows the same logo with the word "twenty" around it, potentially hinting at a belated 20-year reunion following their 2000 debut album One Touch.

Donaghy left Sugababes in 2001, and it was only in 2019 they reunited for a cover of Sweet Female Attitude's "Flowers" with DJ Spoony after securing the legal rights to the Sugababes name again.
