Fashion designer Beckham posted on Instagram on Monday that she wouldn't join the other four Spice Girls on stage again, but wished Geri Horner (Ginger Spice), Melanie Brown (Scary Spice), Melanie Chisholm (Sporty Spice) and Emma Bunton (Baby Spice) well for their six-date tour next year.
"Even though Victoria's not joining us on the tour, she still sends her well wishes and she will be coming along - hopefully, fingers crossed".
"I've always said we're going to get back together", she told Evans. Mel C wasn't sure.
"We really support each other and the decisions that we make and we really support her and she's really supporting us so I think that's a big part of our ethos", she said.
He gushed: "We also have an extra special Spice Girls surprise because I can now reveal that tomorrow morning on Heart Breakfast, the Spice Girls will be here!"
Geri Horner suggested there might be more dates "if Mel B behaves herself".
If you thought you were bummed about the fact that not everyone would be present for the reunion, wait until you see how the Spice Girls feel about Posh skipping the tour. I'm just doing it because I love you ladies! "Breath of fresh air", she said.
They also addressed the rumours that they'd be headlining Glastonbury Festival next summer.
However, Bel B doesn't quite see it that way, and pointed out that she's been calling for a reunion for a very long time.
"Yes! We were in America, we'd gone out for some drinks and we were on our way home in the vehicle and I did feel very ill because I'd eaten something weird and had a few drinks, and I was sick out the window but it blew..."
"Well because she was still talking!"
In a video accompanying the tweet, there was footage of each member apart from Beckham above a ticker headline: "Friendship never ends: Spice Girls announce shock United Kingdom tour".
She was speaking on United Kingdom radio station Heart overnight on a show hosted by fellow band member Emma Bunton (Baby Spice) and Jamie Theakston.
