So, picture this: it's the 80s, the world's gone mad for perms and shoulder pads, and our dear Princess Diana is just a wee lass, right? Wrong! Our Di was already a fully-fledged adult, ready to take on the world - and a certain Prince William.

Diana, the Teenage Sensation

Now, you might be thinking, "But wasn't she just a teenager when she had William?" Well, let me pop that bubble like a royal tiara under a champagne cork. Diana was 21 when she gave birth to the future king. Yes, you heard it here first, folks. Our girl was all grown up and ready to be a mum.

But hold onto your tiaras, because here's where it gets even more surprising. Did you know that Diana was actually older than Prince Charles when she married him? That's right, our girl was a cougar before cougars were even a thing. Charles was a mere 32 when they tied the knot, while Diana was strutting her stuff at a cool 20 years old.

Diana's Royal Pregnancy

Now, back to baby William. Diana's pregnancy was a whirlwind of royal proportions. She was the first royal to have her baby in a hospital (scandalous, I know), and the whole world was watching. The press camped outside Lindo Wing, waiting for that first glimpse of the future king.

And what a entrance he made! William was born on June 21, 1982, and the world went into a frenzy. People celebrated in the streets, and even the Queen herself was thrilled to welcome her first grandchild.

Diana, the Supermum

Diana was a hands-on mum, and she was determined to give her boys a normal life. Well, as normal as it can be when you're growing up in Kensington Palace. She took them to school, played with them in the park, and even let them eat McDonald's (gasp!).

She was also a bit of a rebel, breaking royal traditions left and right. She let William and Harry ride bikes without helmets (shocking, I know), and even let them play with commoners' children. The horror!

William's Early Years

Little William was a cheeky chappie from the get-go. He was always getting into mischief, much to his mum's delight (and sometimes despair). He once told a group of well-wishers that he was going to be an engine driver when he grew up. Bless!

And let's not forget the time he stuck his tongue out at the paparazzi. Now that's a future king we can get behind. Diana, of course, was mortified, but we think it's hilarious. Keep 'em laughing, Wills!

Diana's Legacy

Sadly, Diana left us too soon, but her legacy lives on in her boys. William is a spitting image of his mum, both in looks and kindness. And let's not forget Harry, who's following in his mum's footsteps with his charity work and love for the common folk.

So there you have it, folks. Diana was a grown woman when she had William, and she was a darn good mum too. Now, who's ready for a royal tea party?
