Kate Middleton’s secret to a slim post-baby figure revealed!

The last time she was seen in public was at a charity polo match on Sunday, playing with her son Prince George, while her husband Prince William and brother-in-law Prince Harry took part in the game.

At the event Kate was wearing skinny jeans after just one month since Charlotte’s birth.

So what is her secret for a slender figure in such a short time? According to People, the Duchess, 33, has worked with a top trainer while she was pregnant, and she also had a healthy diet.

And for “an extra boost” of energy, Kate reportedly drinks green juices, delivered by her sister Pippa Middleton.

Catherine has always had an enviable figure.
