Harper Beckham showed off her ‘matching tattoo’ with oldest brother Brooklyn’s wife Nicola Peltz as she celebrated her 12th birthday on Monday.

In one of the snaps shared by Nicola in her birthday post for Harper, the daughter of David and Victoria Beckham held up her white T-shirt revealing a stick on butterfly inking which matched her sister-in-law’s one on her lower back.

Taking to Instagram, Nicola shared the sweet throwback snap to mark her ‘baby sis’ special day and gushed how much she loves her.

She penned: ‘Happy birthday to my baby sis Harper 7. You are the most amazing girl I am so lucky to have you in my life.

‘I love you more than you even know! (Can we always match forever??)’

It comes after Harper’s famous parents took to Instagram to share a sweet tribute to their daughter to mark her birthday.

The former footballer, 48, and fashion designer, 49, shared a carousel of sweet pictures and videos featuring the youngest of her four children.

The adorable reel featured a slew of clips and snaps from Harper’s life, including cute images of the pre-teen cuddling her older brothers and her proud parents.

Doting dad David captioned the post: ‘Happy Birthday my pretty lady, keep being beautiful inside and out, you are the most amazing little girl a daddy could wish for, Daddy loves you’.

While Victoria wrote: ‘Happy birthday baby girl!!! Can’t believe Harper Seven is 12 today!!!! We love you sooooo much!! You are our everything.’

Her older brother Romeo, 20, also shared a photo of the pair on Instagram to celebrate his little sister’s special day.

He wrote: ‘HAPPY 12th birthday harper seven I love you so much.’
