The 37-year-old star - who shot to fame in the girl group in the 1990s alongside Victoria Beckham, Geri Halliwell, Mel B and Mel C - is confident the '2 Become 1' hitmakers will reunite again at some point in the future following their successful one-off performance at the London 2012 Olympics.
She exclusively told BANG Showbiz: ''I'd love to do something like that again. That's the thing with us, we do love working together.
''But it's very difficult now being so busy. But I think when the right opportunity comes up then we will go, 'Right, lets work this out.'
''But I don't know when this will be or if it will be but I love working with them.''
The blonde beauty insists the whole group all get on really well because they have a ''very special bond'' and admits they will not be able to stay away from music forever, even though fashion designer Victoria has appeared to distance herself from her music career.
She added: ''Victoria will always be a Spice Girl, always. She loves it. But we are all doing different things. I think it's just about doing different things. But I'm sure we will do something again at some point.
''There's a very special bond between us. You can't keep us away.''
Corgan took to Instagram to confirm rumours of new Pumpkins material, saying the first songs could arrive as early as May.
