Looks like Kate Middleton just spilt some major royal baby news!

While visiting the public in the coastal town of Grimsby in the UK, the Duchess may have accidentally revealed what we’re all dying to know – is it a boy or a girl?

After accepting a teddy bear from a woman in the crowd, Kate followed up with: “Thank you, I’ll take that for my d…”

Unless she was talking about her dog…it sounds like a royal daughter is on the way!

Someone else in the crowd jumped in asked if she was indeed about to say “daughter” – to which Kate quickly replied “no, I don’t know.”

Prince William then nipped it in the bud by confirming that no, they’re not telling.

What do you think? Are they having a girl?
