The group's first lineup - consisting of Keisha Buchanan, Siobhan Donaghy and Mutya Buena - will reportedly release a single in the summer with the record following later in the year.
Donaghy tweeted: "Thanks for your kind words. There will indeed be another record out in the autumn with a single in summer."
While a reunion of the original lineup has yet to be confirmed, each member has tweeted about recording new music together.
Singer-songwriter Emeli Sandé recently announced that she has written a track for the group, whose new name has yet to be decided.
Meanwhile, Heidi Range told Digital Spy earlier this year that the current Sugababes have not split up, but are not concentrating on music at the moment.
