Adwoa, whose parents are fashion agent Camilla Lowther, cousin of the late 8th Earl of Lonsdale, and location scout Charles Aboah, looked nothing short of sensational in a black bikini, which she paired with a loose, matching maxi skirt.

The Vogue cover girl swept her dark locks back in a low bun as she tucked under a black baseball cap.

Meanwhile, Cara wowed in a plunging navy swimsuit and denim shorts during the fun-filled celebrations at sea.

Cara was in good company as among her famous friends on the trip were Sienna Miller, 40, and Margot Robbie, 32.

After the fierce battles on the boat, which Cara didn’t seem too impressed with, Adwoa slipped into a flashy sparkling pink bikini.

The model showed off her incredibly toned physique in the two-piece as she walked down the yacht’s steps ready for a swim in the ocean.

The model pulled out all the stops for her 30th birthday with an extravagant blue and gold six-tiered cake.

The Londoner, who wore a sheer white dress to the bash, was joined by a host of friends including model Cara Delevingne, with whom she shared a hot kiss.

Adwoa is dating US skater Daniel Wheatley, 33, with whom she has been dating since last year.

Speaking about her friendship with Cara, Adwoa previously told Glamor: “People call us ‘model best friends,’ but we were friends before.

“What I’ve always been grateful for is that we don’t expect anything from each other, just friendship.”

Adwoa previously opened up about her insecurities in social situations, claiming that she felt “not white enough and not black enough” during her teenage years.

On the cover of Elle magazine, Adwoa confessed to the publication, “I would watch from the sidelines as certain friends thrive in social situations, all carefree and radiant as I quietly hid my insecurities and internalized my shame.”

“Like many others before and after me, I never felt like I belonged. I wasn’t white enough, nor was I black enough. Guys didn’t go for my braids, so I adapted – by painfully relaxing my hair, which didn’t convince them either.

Based on her experiences at school, she admitted her strong desire to “be like everyone else”, but failed many exams.

She wrote, “By school standards, I wasn’t strong academically, pressures only compounded by my dyslexia and the multitude of exams I failed.”

Adwoa said she wanted to “adjust to be like everyone else,” which would ironically be “a massive detriment to my career today” but was her “deepest fantasy” at the time.
