She looked incredible on a family day out with son Prince George and husband Prince William at the weekend.
Just six weeks after giving birth to Princess Charlotte, the Duchess of Cambridge showed no hint of a baby bump in her laid-back outfit, consisting of fitted striped tee and skinny jeans.
But Kate Middleton’s post-baby weight-loss journey hasn’t been plain-sailing, as it’s been reported that she’s hired an elite personal trainer in a bid to shift the pounds, according to People.
Catherine, 33, is reportedly paying ‘a lot of money’ for the London-based personal trainer, who’s popular with A-listers and fellow royals.
The Duchess of Cambridge, who gave birth to Princess Charlotte on May 2, speaks to her trainer on the phone every day and they meet up for weekly workouts – although it’s not known whether she has to endure burpees and bear crawls like the rest of us.
Her diet consists mainly of organic fruit and veg, as well as lean meat, although the food is reportedly ‘very elegant' (which apparently means it tastes like restaurant food!).
The report states that Kate’s trainer, who has not been named, was brought on board during her second pregnancy.
It’s thought that the mother-of-two will breastfeed her daughter, as she did with Prince George, which will also help ditch the pounds.
Celebrities including Scarlett Johansson and Mila Kunis also credit their incredible post-baby bodies to breastfeeding.
But we can't all snap back into shape like Kate and co, with many women struggling to shift the pounds after giving birth.
In fact, Prince William's cousin, Zara Phillips - who gave birth to daughter Mia in January 2014 - was forced to deny she was pregnant after pictures of her surfaced wearing a rather ill-fitting dress to the races.
