"Harper and daddy (with a major tan going on!!) x kisses @davidbeckham x," she captioned the Instagram post, which received plenty of comments from fans in a matter of moments.
Many reacted to Harper's chic outfit, which looked like a purple dress with a black lace overlay - and appears to be a mini-me version of one of Victoria's own gowns.
Victoria confirmed it on her Instagram Story later, resharing a post from Joseph Larkowsky which read: "Harper Seven's custom SS2021 lilac @victoriabeckham dress is the cuteness I need in my life today."

"Happy #NationalLipstickDay! I love a classic red lip. Naturally, my favourite is @victoriabeckhambeauty's Posh Lipstick in Pop. It's the best red!," she captioned it.
After launching her lipsticks in October 2020, the former Spice Girl revealed why she included the bold shade in her line, which mostly consists of more muted shades.

"I was having dinner with Mr Valentino a few years ago in Italy, and he said to me, 'Darling why do you never wear a red lip?'. And I said well because I'm nervous," Victoria said.
She added: "And he said: 'Women should always, always wear a red lip'. And that was a turning point for me, because I was quite intrigued by what he said and wanted to try it."
