Meghan Markle just proved that she's human, like the rest of us.

The Duchess of Sussex accompanied her husband, Prince Harry, at Poppy Factory’s Field of Remembrance at Westminster Abbey on Thursday and accidentally left one veteran with a gift -- her makeup.

Meghan embraced D-Day veteran William Allen with a hug and kiss, and as she pulled away, she left a smudge of her makeup on his jacket -- something anyone who's worn makeup or hugged someone wearing makeup can relate to.

While some would be annoyed at the blemish on their clothing, Allen didn't mind at all, according to Cosmopolitan. And, in his excitement of even getting to meet the mother of 6-month-old Archie, he posed for a photo with it.

"I'm never washing that," he said in reference to the smudge.

Royal correspondent Rebecca English documented the moment on her Twitter account.

"And here is D-Day veteran William Allen - a remarkable man who celebrates his 100th birthday next month," she tweeted. "Meghan hugged and kissed him, leaving a little make-up smudge on his jacket. I’m never washing that!' he said."

It's moments like this that probably help Meghan to remember that not everyone is critical of her. And, perhaps, one of the reasons that would dissuade her and Prince Harry from leaving the British royal family as has been speculated.

Fans aren't the only people the former "Suits" actress can look to for support. Her father-in-law, Prince Charles, whom she's developed a close relationship with, can also help her get through tough times.

"The bond between them is very close," an insider revealed to Vanity Fair recently. "He’s got a real soft spot for her and thinks she’s the best thing to have happened to Harry."
