Britain's Duchess of Cambridge has reportedly lost so much weight that her waist is now less defined.
Catherine and her husband Prince William gave birth to their first child, George, in July.
Since then the 31-year-old has been snapped looking very slim, with the pretty royal managing to keep weight gain to a minimum during pregnancy.
The brunette had all eyes on her when she signed a book in memory of the late Nelson Mandela recently and it's been claimed she looked tiny at the event in London.
"I couldn't believe how skinny she looked in the flesh," a spy marvelled to British magazine new!
"You could see her hip bone poking through her skirt and she has lost definition in her waist. She looked a lot healthier back when she had a bit more meat on her."
Despite concerns for her welfare, it's generally agreed that Catherine makes a gorgeous new mother.
The royal is known for wearing pieces from high street stores such as Zara and Reiss and was crowned the best-dressed mum by website FashionPerks earlier this year.
A spokesperson for the website, Max Bramwell, says Catherine received overwhelming support in their survey.
"It's testament to how dearly the British public hold the Duchess of Cambridge to their hearts," Max told Grazia Daily. "She's only been a mother for a matter of weeks, and had barely been seen in public since the birth, yet people are still drawing on her example for inspiration."
Catherine beat a whole host of other stylish star mums including Angelina Jolie and Kim Kardashian to take the title.
