And Katie believes the royal couple will be having a "very modern" nursery with no pink or blue, as they want to keep the room as unisex as possible.
She added: "The couple has said that they don't know the sex of their baby. Meghan gave away a little detail that we've all been hoping to hear, that it's going to be a spring baby.
They've decided not to find out the sex, but according to sources who are helping with [their new home] renovations, the nursery itself is going to be very modern.
Don't expect to see any baby pink or baby blue. Apparently, it's going to be a monochrome palette - whites and greys, I'm told, will be the colour theme for baby Sussex's nursery."
