It runs in the family! TOWIE's Sam and Billie Faiers show off their VERY good genes as they parade incredible bikini bodies on the beach in Dubai

Bikini babes: Sam and Billie Faiers showed off their killer bodies as they lapped up the sun on the beach in Dubai

Sam, 22, showed off her toned tum and killer tan in a khaki fringe-detail halterneck number as she enjoyed a day at the beach with her elder sister.

Piggy-back: The blonde sisters seemed to be in great spirits as they frolicked together in the turquoise ocean

Genetically blessed: The TOWIE co-stars looked positively stunning as they kicked back on the white sands at the Le Royal Meridian Hotel

Not to be outdone by her younger sister, Billie, 23, looked equally as impressive as she enjoyed a dip in the perfect turquoise sea.

The boutique owner looked as though she had been hard at work in the gym as she flashed her toned and taut stomach in a skimpy burgundy string bikini. 

With her locks highlighted by the sun, the blonde bombshell had the beach babe look down to a tee as she soaked up the rays. 

Playful: Billie couldn't help but giggle away as her sister splashed her with water

It runs in the family: Sam showed off her toned tum in a khaki fringed two-piece, while Billie paraded her enviable curves in a burgundy string bikini 

The girls seemed to be in fantastic spirits as they enjoyed a day at the beach together, with the pair playfully splashing each other before Billie jumped on Sam's shoulders for a piggy-back.

Although there's no denying both girls looked incredible as they displayed their bikini bodies, both have admitted to suffering from insecurities in the past. 

Speaking about her 32G bust, Billie said: 'I’m 5ft 4in and a size 8 with massive boobs, so when I started on TOWIE everyone wrongly assumed they were fake.

Sister act! The girls had evidently spent a lot of time soaking up the sun, with both of them sporting killer tans during their day out at the beach

'My back constantly aches and my shoulders tense up with the weight of them. It builds up during the day and by night-time, it’s really painful.'

Meanwhile, Sam admitted she and her sister have accepted that they'll never be 'stick insects'.

She said: 'My confidence differs from week to week. Some weeks, I feel good and other times I don’t. I try not to focus on bad pictures, though. 

'We’re not stick insects and we’d never want to be. We go out in flats and no make-up and we’re just ourselves.'

Killer curves: Billie looked as though she had been hard at work in the gym as she showed off her flat stomach and toned limbs
