Twitter got excited last week after a tweet by CBS Miami reporter Lisa Petrillo claimed she spotted Meghan, the Duchess of Sussex, walking her dog close to Kensington Palace.

A woman who resembles Meghan can be seen walking a dog, Petrillo claimed that the woman even scooped up her dog's poop.

But it's now been revealed that the snap that got everyone excited was, in fact, a case of "mistaken identity". Royal commentator Omid Scobie tweeted that the Duchess is not the woman in the dog-walking picture.

Scobie told BAZAAR.com, "Right time, right place, but I’m afraid it’s not the Duchess in that photo."

Fans, however, were not convinced because they believe Petrillo wouldn't make it up.

Meghan is also a self-confessed dog lover, and the Royal couple reportedly adopted a Labrador after the former actress' beloved beagle named Guy who now lives with friends since she moved to UK after marrying Prince Harry.
