Emma Bunton is ''up for'' another Spice Girls reunion.

The 'Stop' singer - who was known as Baby Spice - is willing to reunite with her bandmates, Victoria Beckham, Mel B, Geri Halliwell and Mel C if the right opportunity came along but doesn't know if they could top their performance at the 2012 London Olympics Closing Ceremony.

Speaking to BANG Showbiz, Emma explained: ''It's not something we have talked about. I love working with the girls, I would be up for it. It's all about timing. We did the Olympics - it's quite hard to top that!''

The 38-year-old radio presenter admitted that keeping in contact with her old bandmates can be tricky given their extremely busy schedules.

She said: ''It's very difficult as we have own families. I definitely see them as much as I can. I spoke to Mel C the other day and I saw Geri a couple of weeks ago.''

However, after Victoria's successful clothes auction - which was in aid of the charity mothers2 mothers - Emma is sure that an auction of Spice Girls memorabilia would happen in the future.

She said: ''Yeah, I am sure that will happen. I would have to have a rummage in my mum's loft!''

Emma is proud to be part of the '1 pack = 1 vaccine' campaign where for every pack of Pampers sold, Pampers donates the cost of one maternal and newborn tetanus vaccine to UNICEF.
