Is a third royal baby on the way?

Rumours have not stopped swirling the Duke and Duchess of Cambridge are expecting their third child.

But now Kate has added fuel to the fire by "joking" about having another baby.

According to The Sun, when the royal couple landed in Poland on Monday, a Polish fan handed them a toy meant for a newborn.

Kate apparently laughed it off and said "we will just have to have more babies" to William.

Julia Sielicka-Jastrzebska, who's in charge of the firm that made the stuffed bear Kate was gifted with, said the toy is designed to help comfort newborns by imitating sounds from a mother's womb.

The Internet has already gone into meltdown dreaming there will be an another adorable royal baby soon enough.

It has been two years since Kate gave birth to her second child, and a source has further revealed that the couple wants to have another baby.

"They want at least three kids and for them to be close in age," said the insider.

They did just add a massive extension to their home, though, which sounds like the perfect place for a nursery. Just saying...
