In an appearance on BBC Breakfast ahead of rehearsals for the reunion tour, Bunton said that the band are all “so tight.”
She added: “We have been in this industry for a very long time, we know how it all works. We constantly talk on the phone.
“If something comes up, we’re like ‘What’s going on?’ We are like family. We talk about everything, we get it out in the open and then it’s done!”
Emma revealed that the bandmates are all so close they’re more like sisters, due to their shared past.
She said, “Honestly, we are so tight that even my family when they see us together they’re like – there’s a connection there that no one else has.
“I can only speak to them about the things we have been through. They’re like my sisters, I spoke to Geri and Mel B last night.”
Mel B has rowed back her comments about her fling with Spice Girls bandmate Geri Horner, claiming that the press have taken it ‘to a whole other level’.
Mel, real name Melanie Brown, claimed that she and Geri once slept together during their time in the band in an interview with Piers Morgan for this ITV talk show.
Speaking to the 2Day 104.1 radio show in Australia, she said: “I didn’t actually really admit anything.
“I just said we had a ‘thing’. It wasn’t a big deal. It was one of those things that happened one night.
