Reports last week suggested that Mutya Buena is keen to re-form the girl group with Keisha Buchanan and Siobhan Donaghy.
Cole also said that she was "sad" to hear that Buchanan had quit the band, says Angry Ape.
"I've always loved the Sugababes - since they started. It's strange now because the original three members could get back together... that could be interesting."
She added: "As a brand, they are fantastic and as long as their music continues, I think they will."
