Everyone's convinced they know what William and Kate are going to call their third child

We're only two months away from the birth of Prince William and Kate Middleton's third child. TWO MONTHS. So naturally, part of Royal Baby fever involves eagerly guessing the gender and name of the new little heir to the throne.

But it seems it's all gone up a gear recently. People have become so convinced they know what George and Charlotte's new baby sibling will be called, the bookies have suspended bets.

What will the fifth member of the family be called?

So what are they all putting their money on? *Royal drum roll please*: Mary.

Both Paddy Power and Betfair have lowered the odds for the Duke and Duchess' third child being given the name Mary from 12/1 to 3/1. That means they believe it's four times more likely to be the chosen moniker for the new member of the monarchy. Betting shop Coral has similarly followed suit, cutting their odds on the name Mary from 20/1 down to 4/1.

And Mary wouldn't be a surprising choice for the new royal kid on the block. Viewers of The Crown/general royal buffs will know that Queen Elizabeth's grandmother was called Mary - and the Queen even has Mary as one of her middle names.

As you can probably gather, the surge of betting means people are pretty sure Prince George and Princess Charlotte are going to have a baby sister, but it's still worth remembering nobody actually knows this for sure. Ahead of the birth of their first child, George, William and Kate decided not to find out the gender - so we can probably assume the same goes with pregnancy number three.

But it's always fun to have a guess anyway - and all the better if you win some money from it. Other favourite names that have been tipped for a royal baby girl include Alice, Victoria, and Elizabeth.

At least we don't have that much longer to wait to find out for ourselves.
