Brooklyn Beckham's fiancee Nicola Peltz is already calling Harper Beckham her "special baby sister" and they are wearing matching rings.
Nicola hinted she's already tied the knot with fiancé Brooklyn Beckham in a cryptic band snap on Instagram on Saturday.
Now she and Harper have matching rings - and the American is already treating the nine-year-old as family.
The model, 25, said "yes" to Victoria and David's eldest son just last month, but speculation swirled that they're already got hitched without the world knowing.
Nicola shared a snap of herself and Brooklyn holding onto a label, and Brooklyn's ring caught the attention of fans.
It resembled a traditional design of a man's wedding ring - and now she captioned her latest photo with Harper: "She's just the most special baby sister".
It's not the first time her soon-to-be sister-in-law has appeared on her social media pages.
Sharing a photo of herself cuddling up to the Beckham's youngest child on her big day, she wrote at the time: "Happy birthday to my favourite girl ever.
"I love you so much Harper Seven."
Brooklyn and Nicola have yet to announce a wedding date - and the fact they are dragging their heels left some fans asking if they really did go for a low-key affair.
The lovebirds spent lockdown together at Nicola's family mansion in the States before Brooklyn decided to ask her to be his wife.
But the chances of them getting wed with no fanfare are very small with what is on offer to do it properly.
The billionaire heiress bride-to-be plans to go big and pull out all the stops for the big day.
Sources say they will splash some serious cash when they do tie the knot.
Brooklyn reportedly kept with tradition and asked Nelson, 78, and Claudia, 65, for their permission.
The mega-rich family - whose wealth dwarfs the Beckhams - are expected to foot the bill.
