Nicola Peltz Beckham documents her close bond with "sister" Harper Beckham

The Beckhams are famously close, and that extends to those married into the family of six. Nicola Peltz Beckham, who married the Beckhams' oldest son Brooklyn last year, shared an adorable moment with her "sister" Harper Beckham backstage at Victoria Beckham's fashion show during Paris Fashion Week. (David and Victoria Beckham, who married in 1999, are the parents of four children: sons Beckham, Romeo, and Cruz, and daughter Harper. Brooklyn is the only married man so far.)

Nicola showed her sister-in-law some love on Instagram on Sunday, captioning a photo of the two of them, "Such a beautiful show with my baby sis." She also gave a shout-out to her mother-in-law, writing, "Congratulations @victoriabeckham."

According to People, in an image of Nicola and Harper, they leaned against each other while standing in front of a mirror backstage at a show held at Karl Lagerfeld's former townhouse for Chanel They were leaning against each other.

Victoria commented on the post, writing, "Love this look on you! Incredibly beautiful! Kiss me xxxx". Nicola wore a black bralette, gray pencil skirt, and fishnet stockings, while Harper wore a long cream dress. Nicola and Harper sat front row at the Victoria show alongside David, Brooklyn, and Cruz. Also during her stay in Paris, Nicola spent quality time with David's mother, Sandra Beckham. Nicola shared a photo of her and Brooklyn kissing Sandra on the cheek with the caption "paris love," accompanied by 15 heart emojis.

Back to Nicola and Harper, the two "continued to spend time together bonding in the UK over the weekend, visiting pubs with chef Brooklyn and Nicola's father, businessman Nelson Peltz," People reported. Nicola, in a video eating sausage, mashed potatoes, and gravy, wrote, "Brooklyn took me to his local pub today, and we had a great time...we had a great time.

Family time continued with afternoon tea. Nicola posted an image of finger sandwiches and scones to her Instagram Story with the caption "Best afternoon tea everrrrr." She was joined out by Sandra Beckham, Victoria's mother Jackie Adams, Brooklyn, and her mother Claudia Peltz.
