Rochelle Humes was told to go on a diet when she started dating husband Marvin Humes

Speaking about the harsh criticism she received on Giovanna Fletcher's podcast titled 'Happy Mum, Happy Baby', the brunette beauty said: "I was in a girl band with teeny tiny people. I was already taller than them and you always feel bigger don't you. But now I look back and think if I could have shook your younger self, you were great. What I would do to look like that now.

"I remember old management telling me when I met Marvin that I'd put weight on. Telling me that I needed to go on a diet and I remember thinking 'Oh'."

The 'Up' hitmaker - who has four-year-old daughter Alaia-Mai and six-month-old Valentina with her spouse - hopes her brood do not face the pressure to be a certain size when they grow up.

Meanwhile, Rochelle is back in the gym working up a sweat as she has signed up to run in the London Marathon on April 22 next year, which will see the star raise money for Teenage Cancer organisation.

Alongside a video of the 'Ninja Warrior UK' co-host in her workout attire training with her personal trainer, which was previously shared on her Instagram account, she wrote: "So DAY 1 of training for the #londonmarathon with @pmacfitnesslooked like this... I'm running for @teenage_cancer Really hoping raise lots of money for them, I'm also hoping to get better at running. Any tips or advice anyone has will be greatly appreciated lol Comment below #teamlegend @nokwamz (sic)."
