Mel B Says Not Everyone in Spice Girls is 'Honest' Enough for a Documentary

Don’t expect to get a Spice Girls documentary anytime soon … at least not according to Mel B!

This year will mark the 30th anniversary of the girl group’s debut — their first single and album both dropped in 1996 — but Mel is shutting down rumors that she’ll reunite with Victoria Beckham, Melanie C, Geri Halliwell and Emma Bunton for a doc.

She told Hello it’s not that they haven’t been asked or weren’t considering it, but she’s not sure it would get done “in the right way,” saying … “It has to be honest — and not everybody wants to be honest.”

She said … “If it does, it’ll be a shock to me, let’s put it that way.”

Mel explained she doesn’t want to be “nagging” the girls about getting the group back together, noting … “I laid that to rest when I turned 50.”

She’s not even sure that she’d be interested, adding … “I’ve got fond memories, but I don’t know if I would want to go back up on stage.”
