The boutique owner showcased her toned abs and svelte figure in a pink floral print two-piece from high street hero Dorothy Perkins.
The body confident 22-year-old showed off her long ombre hair extensions and looked fierce as she captured her own photo before posting it to Twitter.
And it looks like Sam will be showing off the high street beach wear on her forthcoming holiday to Los Angeles.
She tweeted: "Thank u @Dorothy_Perkins for my bikini. I shall be taking this to LA with me."
We're slightly jealous that Minnies Boutique owner Sam is already planning another holiday, as she's just returned from a girly trip to Ibiza this week (29 July) with best friend and co-star Ferne McCann!
Sam and Ferne enjoyed plenty of sun, sea and sangria on the Spanish island, and partied with fellow co-stars Lauren Pope and Jessica Wright.
Sam also proved that she has impeccable fashion taste, as her holiday wardrobe was filled with gorgeous bikinis and swimsuits.
The break was a good opportunity for Sam to let her hair down following her split with Joey Essex in June, but now with a vacation to LA in the works, we reckon Sam will be giving us some serious holiday envy!
