"We're still talking about it at the moment," she told No White Noise.
"We all wanted to venture into our own things since we all had our little projects in our mind but also in our heads we have been thinking that we're going to get back together.
"Even when I'm in the studio writing, there's definitely a couple that I think, 'Oh, that would be good for us', as in us three. So I'll put a couple of tracks to one side. I'm pretty sure it will happen by kind-of next year."
Berrabah also insisted that she is "happy" the original lineup of the band are reforming, adding: "Especially since all three of them are very talented singers and I really respect vocalists who can actually sing.
"You know nowadays there's a lot of auto tune going on and artists not singing live, so it's nice to see three people getting together again and making some good music. I'm excited for them, and I'm intrigued to hear what they have. I wish them all the luck."
Who even wants this? The GP don't even really consider them the Sugababes anymore. There's a reason MKS is the group receiving the most media and industry attention.
