While we're still not privy to Meghan Markle's due date, we do know one thing: it's very, very soon!

The Duchess of Sussex has been pregnant for seemingly forever, and last month it was announced that she wouldn't be making any more public appearances until after her little bundle of joy arrives, meaning that she's likely due any day now.

But the due date for when Baby Sussex will arrive is just the start of the list of 'Things We Don't Know.' One other major detail that's being kept from us is the child's gender.

Will the UK be getting a little boy or girl? There are few people who know the truth, but one of these people is likely to be Serena Williams - and the tennis champion may have let the cat out of the bag!

During a recent interview, Meghan's long-time friend was being questioned on motherhood and was asked what her advice to new mums out there would be.

She advised them to accept mistakes and not expect to be perfect - but then carried on to say: "We put so much pressure on ourselves. My friend is pregnant. And she was like, 'My kid’s gonna do this,’ and I just looked at her and was like, ‘No, she’s not. No, you’re not.'"

"And she started laughing and was like 'Well I need to talk to you about tips. I'm like 'yes' because I had all those high expectations. I had what I was going to do and how I was going to recover and I was going to be great. But it's like, this is a time that everything is not going to go as planned. My whole life is so planned and this is the one time it wasn't and you just have to go with the flow."

So, did you catch it? If you didn't, please note that Serena used the pronoun 'she' in reference to her friend's baby and then quickly switched to 'you're'. Does this mean that we have a new little female royal on our hands? Some people seem to think so!

Of course, it must be pointed out that there are many flaws to this theory. Number one: Serena may (quite easily) have another pregnant friend.

Media outlets reporting on the interview have been racking their brains to think if there is another famous person who has a baby on the way and is friends with Serena. It seems not.

Flaw number two though: Serena could (very easily) have a non-famous pregnant friend.

So all-in-all, you have to admit, the athlete's 'slip-up' may not have been such a big give-away as first perceived.

But also... how cute would a little Meghan be?!
