Emma Bunton recalls lactating through Robert Cavalli dress during Spice Girls tour

Emma Bunton once started lactating through her Roberto Cavalli dress during a Spice Girls show.

Emma reunited with Victoria Beckham, Mel B, Mel C and Geri Halliwell for The Return of the Spice Girls comeback tour in December 2007, four months after she had given birth to her son Beau.

In an extract from her new book Mama You Got This: A Little Helping Hand For New Parents, Emma shared her memories of lactating "quite heavily" during one of the tour's early shows at the Staples Center in Los Angeles and running off stage to grab pads to protect the designer dress.

"Our costumes had been designed by Roberto Cavalli, who Victoria knew, and oh my goodness they were beautiful," she wrote, reports The Sun. "But stage costumes are different to evening wear. These were heavy, highly structured pieces (they had to withstand quite a lot of activity!) and there were frequent changes.

"I remember it happened during Say You'll Be There - I was wearing a rose-gold dress with an empire line and a high neck, with gold lame that was quite close-fitting over my boobs. I had to get through a whole other track, Headlines, just hoping nothing was showing. As it ended I came running off stage screaming at (partner) Jade (Jones), 'Babes, get the pads! Get the pads!'"

And she made it backstage just in time - before her milk had made too much of a wet patch on the dress.

"Luckily, as it turns out, gold lame isn't very porous and most of the milk had just drizzled down my stomach. But anyone looking close enough would definitely have been able to spot wet patches on my boobs during that number," she shared. "I can look back and smile about it now, but when I look at the pictures I also see a woman who really wasn't ready to be throwing herself into that kind of physically demanding regime."

Emma and Jade are parents to sons Beau, 13, and Tate, 10.
