Scary Spice confirmed that she is the driving force behind a potential comeback for the girl group in 2016 - and it will only happen if it's all five of them, Posh included.
"Nothing has been announced, nothing's official. Yes, we are in talks, because it is our 20th anniversary, and I want something to happen - it better," Mel told US talk show host Meredith Vieira.
"I'm forcing them a little bit - I've been saying it for five years. 'We are reuniting, aren't we? We are? We are? We need to!'"
Responding to rumours that Victoria Beckham doesn't want to be a part of the reunion and that she has fallen out with the girls as a result, Mel B wasn't having any of it.
"She is my friend, I adore her, I love her to pieces. If we do something, it has to be all of us. That's the whole point. As soon as there's something to actually announce, I'll be yelling it from the rooftops!"
Geri Halliwell let slip last week on This Morning that the Spice Girls were in talks for a reunion, so let's hope they can sort out something soon.
