Mel C wants the Spice Girls to perform in London's Hyde Park next year.
The 41-year-old singer - who starred in the chart-topping group alongside Mel B, Emma Bunton, Geri Halliwell and Victoria Beckham - revealed the group has already held talks about getting back together and she admitted the open-air venue would be an "amazing" place to do it.
She said: "We've talked about it, but we just haven't got our act together.
"We're a bit useless. But performing at Hyde Park would be amazing.
"I went to see Taylor Swift there this year and it was so wonderful. It was a really good, fun gig. I think for the Spice Girls that would be appropriate. It's a bit more friendly."
However, Mel rubbished speculation they'll reunite for the annual Brit Awards in February because she doesn't think they could be ready in time.
The singer - who was known as Sporty Spice during her time with the group - told the Daily Mirror newspaper: "There's definitely no chance we'll get our act together by then.
"It's a shame, actually. We need to stop procrastinating and get on with something."
Meanwhile, Mel B recently said a Spice Girls reunion must feature all five members of the group, following speculation Victoria does not wish to be involved.
She insisted: "If we do something, it has to be all of us. That's the whole point."
