Nicola Peltz has thanked her brother Will for 'officially giving me my dream sister', after using the same term of endearment for Harper Beckham.

Nicola, 31, shared a gushing Instagram post on Monday dedicated to her older brother and his new wife Kenya Kinski-Jones following their recent wedding.

Four years on from Nicola's marriage to David and Victoria Beckham's son Brooklyn, her brother Will Peltz, 40, married into the family of legendary record producer Quincy Jones when he tied the knot with model Kenya, 33.

Nicola told fans that 'this wedding was truly one of the most beautiful things i've ever had the privilege of witnessing' in her lengthy Instagram post, before thanking 'willy' for finally and officially giving me my dream sister, ken.'

Just two years ago Nicola, who also has her own sister Brittany, called Harper, the 14-year-old sibling of Brooklyn, 'my dream little sister.'
