Poppy Delevingne showed off her model physique in a floral cut out swimsuit as she celebrated her sister Cara’s 30th birthday in Formentera on Friday.

The 36-year-old seemed in high spirits as she joined stars including Sienna Miller, Margot Robbie and Lady Mary Charteris for the wild celebration on a lavish yacht. Poppy sizzled as she partied in the plunging crossover pink one piece which donned green palm trees on.

She showcased her beauty by wearing a radiant palette of makeup while hiding behind a pair of large dark sunglasses. The socialite styled her shoulder length blonde tresses in natural waves as they fell from a centre parting.

Poppy accessorised with a pair of gold hoop earrings and kept a black hair tie on her wrist ready to sweep her locks out of her face.

The actress beamed as she removed a pair of high waisted blue denim shorts which featured a fray hem line.

She was later spotted jumping into the ocean and sitting on a paddle board with her model friends. Also in attendance of Cara’s big day was Sienna Miller, Margot Robbie, Adwoa Aboah and Lady Mary Charteris.
