Emma Bunton reveals which Spice Girl can’t keep secrets

This one Spice Girl would rather “roar” than keep a secret.

Emma Bunton revealed none of the other Spice Girls will tell Melanie Brown, also known by the nicknames Mel B and Scary Spice, anything they want to keep secret.

Bunton, who appeared on ITV’s This Morning on Monday to promote her upcoming celebratory tour, was asked by the show’s host if there was an upcoming documentary about the Spice Girls – which Mel B seemed to reveal while being interviewed by The Project.

“We’ve had talks about pursuing a PhD but nothing has been confirmed yet,” said the 46-year-old singer, aka Baby Spice.

“There are things in the pipeline, and we’d love to do something together again — all of us,” she said.

Bunton said she and the other Spice Girls love how “excited” Brown – who recently announced her engagement to longtime partner Rory McPhee – talks about plans, but they know she’s easygoing.

“But if we want something to be kept secret, we don’t tell her,” the singer joked.

Bunton will begin her tour alongside her husband in December, although it is currently unknown if any of her bandmates will be performing.
