The Spice Girls brought Girl Power to the masses in the late ’90s with style, sass, and a string of bangers seldom equaled in the history of pop.

Now, 18 years after first leaving the band, Geri Halliwell Horner (a.k.a. Ginger Spice) shares her candid thoughts on each of her Spice sisters in an exclusive clip from this Saturday’s episode of Oprah: Where Are They Now?

Horner says that
Victoria "Posh" Beckham was “quite shy” in the early days, but even then showed hints of her financial savvy. “What I loved about her was that she was a good business woman. I felt that she was incredibly astute about those kinds of things.” So it’s little surprise that Beckham has gone on to have an ultra-successful second career as the owner of her eponymous clothing line.

She also praised Melanie "Sporty" Chisholm for the “vitality” she brought to the songwriting process and Emma "Baby" Bunton‘s strong vocal abilities. “I think she’s an amazing singer. I like her tone,” she says.

And Horner’s got nothing but love for Melanie "Scary" Brown, whom she describes as “the leader in your battalion.”

“Mel B is an absolute performer. She’s amazing! When we did the [2012 London] Olympics, she completely carried that. She would add something that was so bizarre and brilliant.” She says that the idiosyncratic “zig-a-zig-ah!” refrain from their breakthrough smash “Wannabe” was Brown’s contribution.

During the show, Horner also reflected on how she first came to join the quintet that would propel her to superstardom. Incredibly, it all came down to answering an ad in the back of a newspaper!

Although it’s difficult to believe, the Spice Girls’ debut “Wannabe” turned 20 years old this summer. Check out what the rest of the Spice Women are up to now.
