The Biggest Clue Yet That Meghan Still Hasn't Given Birth

Prince Harry heads to the London Marathon and we can take that to mean that the baby hasn't been born yet...

Speculation continues to swirl about the due date of Prince Harry and wife Meghan's baby -- with many believing the bub was already here and being hidden by the new parents until a reveal when they felt ready.

But now, that's all in question, because Prince Harry turned up at the London Marathon yesterday -- royal watchers suggesting that if he DIDN'T head to the race, then it was a sure sign the new addition had already arrived.

The new dad/father-to-be cheered on runners taking part in the Marathon on Sunday as Patron of The London Marathon Charitable Trust. During his visit, Harry met with volunteers, watched some of the runners and presented medals to the London Marathon and Wheelchair winners, including the World Para Athletics World Championship Marathon.

“He had always planned to go but with the birth of his child due it was not announced in advance in case he was no longer able to attend. He was pleased he was able to attend,” a palace spokesperson told People, kind of putting those "already born" rumours to rest once and for all.

Meghan was nowhere to be seen, understandably, but it seems all is well with the mum to be -- she recently hosted in-laws Kate Middleton and Prince William at her new Frogmore Cottage home.

Kate and William, who are parents to Prince George, 5, Princess Charlotte, who turns 4 on May 2, and Prince Louis, who turned 1 on April 23, joined Harry and Meghan at their nearby new home following the traditional Easter service nearby.

This marked the first time Kate and William saw the Sussex newly renovated cottage, which was transformed from a staff residence once set up as multiple apartments into a single-family home of about five bedrooms.

Harry’s participation at the London Marathon comes days after he made a surprise appearance on Thursday when he and Kate teamed up for the Anzac Day service at Westminster Abbey while Wills was in New Zealand.

Hurry up baby Sussex... we're all waiting.
