The sizzling zip detail two-piece is by hot celebrity favourite, Beach Bunny - the US brand loved by the likes of Vogue model, Kate Upton, Danielle Lloyd and fellow TOWIE babes Billi Mucklow, Jess Wright and Jasmin Walia, to name but a few.
Despite being desperate to get our hands on Sam's lush blue bikini, it's proved so popular it's sold out everywhere.
