Celebrity blogger Perez Hilton reports that the trio are contractually obliged to produce a new disc for their label.
But it could be at least a year before Kelly Rowland, Beyonce Knowles and Michelle Williams, get back into the studio, it is suggested.
Formed in 1990, the girl group took a break from each other in 2002, only to return with Destiny Fulfilled in 2004.
They disbanded "permanently" a year later.
But a "well-placed insider" told Perez Hilton: "They still have another album they owe the label, Columbia Records, on their contract".
The gossip website puts 2011 as the likely year of the reunion.
