Geri said: "I love her honesty".
Brown said she had dreamt about the band getting back together.
Speaking of Victoria, she may have screwed her old girl band in more ways than one.
She started laughing as she revealed she was the culprit and blamed the mishap on having "eaten something weird" and having a "few drinks". "And we were on our way home in the auto and I did feel very ill because I'd eaten something weird and had a few drinks", Emma explained.
Mel C was quick to point out that she was "fibbing".
"Because she was still talking", joked Bunton. If she had kept her mouth shut for five minutes it might not have blown in'. @OfficialMelB discusses new @spicegirls album!
Geri Halliwell, Melanie Chisholm, Emma Bunton, Melanie Brown and Victoria Beckham pose after unveiling a Virgin Atlantic Boeing 747 plane named "Spice One" in honor of the pop group at Los Angeles global airport on December 12, 2007.
The "Hello" singer has never made a secret of being a Spice Girls superfan, and her epic throwback merely cemented her claims.
The Spice Girls had music fans cheering Monday morning when they announced a summer 2019 reunion tour. I know they will put on an awesome show and the fantastic fans past and present are going to have a wonderful time! X vb #spicegirls #friendshipneverends (sic)'.
Sitting down on Heart Breakfast radio talk show, on which Emma Bunton is a co-host, the girls had nothing but lovely things to say about their missing bandmate.
"I've always said we're going to get back together", she told Evans.
Mel C, aka Sporty Spice, noted that she too was hesitant to join up with the group for this reunion, saying, "There were times, like I mentioned earlier, I wasn't sure, and we really supported each other and the decisions that we make".
However, she was involved in the group's short-lived reunion in 2007 and appeared with them at the closing ceremony of the London Olympics in 2012.
Since then, speculation has been rife that the girls will be re-forming, with rumours reaching fever pitch in 2016 - as it marked 20 years since the release of the girls' first single.
As previously reported, the Spice Girls will tour will hit Manchester, Coventry, Sunderland, Edinburgh, Bristol and London next June.
