She’s left The Saturdays behind her and gone on to TV presenting, family life and writing children’s books.

Rochelle Humes shot to fame with the all-girl singing group, but today co-hosts Ninja Warrior UK, has her own radio show on Heart FM and is married to JLS star Marvin Humes.

Now the mum of two daughters has also penned her debut children’s book, The Mega Magic Hair Swap, which is published this week.

She will be meeting fans in Kent the first weekend her book is on sale, when she heads to Waterstones in Bluewater’s West Village on Saturday, February 9.

Published by Studio Books, The Mega Magic Hair Swap tells the story of two friends with one wish. Mai and Rose are best friends but they’re two peas in a pod. Mai is a curly-haired brunette, while blonde Rose’s hair is poker-straight.

When a magical coconut grants each girl their wish, and they get the hair they’ve always dreamt of, they’re overjoyed. But is it what they really want? In fact, their hair was pretty magical and perfect the way it was before.

Rochelle will be meeting fans at 11am. Fans will need a copy of the book to meet her. For more details call 01322 624831.

The Saturdays singer (the group has been on a break since 2014) has shown her mettle as a TV presenter, having filled in for Holly Willoughby on This Morning while she was in the jungle, become a fashion and beauty brand ambassador, and is set to co-present a new Saturday night music quiz show, The Hit List, with her husband Marvin Humes later this year.

The bubbly 29-year-old's debut children's picture book, The Mega Magic Hair Swap! - is a story about girls, curls and celebrating difference, which she hopes will be the first of a series.

"It came about because my daughter was going through this phase where she didn't like her hair, and was noticing the fact that she was a little bit different to her best friend and the friends in her class. It started off with hair and then it was skin colour. She wanted hair like her best friend at school," she says.

"I would make up these little stories as mums do - and then The Mega Magic Hair Swap! was born, but with a good moral. I think it's bigger than hair. The moral is to teach kids to be who they are."

Her own parents divorced when she was three, and says she had times growing up when she felt different from other children.

"Everyone goes through a phase where the grass is greener, but with age you become more comfortable in yourself, from what you look like to how you approach situations. You learn to love and appreciate what you've got."

A shy child with a stutter, she says she's still not quite sure why she went into showbiz.

"I had a full-on stutter when I was little and went to speech therapy, and they encouraged my mum to send me to a dance or acting club to bring me out of my shell," she recalls.

By the time she joined S Club Juniors aged 12, the stutter had gone and Humes was on the road to fame. But her upbringing kept her grounded.

"I was brought up with my mum working every hour God sends, and it's important to show children that you have to graft. But I'm winging it like everyone else."

She and ex-JLS singer Marvin, 33, share childcare duties, with the help of their family network. The couple were both singers in successful groups and both have gone on to be TV presenters.

"I'm his biggest cheerleader ever and he's totally mine. When you're in a comfortable relationship, when he's done well, I feel like I've done well myself."

She adds: "Mum guilt is such a normal thing, whether you're a working mum or a stay-at-home mum. My friend feels guilty because she's not providing and feels that she's not showing her kids that working is good. That's the nature of being a woman. You just put pressure on yourself."

The Mega Magic Hair Swap! by Rochelle Humes is published by Studio Press Books and costs £6.99.
