Whitney Port “Floral Bikini” Bottoms on Miami pool

Earlier that afternoon, Whitney, wearing a pair of dip-dye cutoff shorts and a green jumper, warmed up poolside by indulging in a tropical cocktail with her female friends.

Whitney will join Elle Macpherson, Julian Macdonald and Tyson Beckford as a judge on Britain and Ireland's Next Top Model this season.

The 27-year-old star first appeared on The Hills alongside Lauren Conrad as a Teen VOGUE intern, before landing her own MTV reality show, The City in 2008, which also helped launch the careers of fellow fashionistas Olivia Palermo and Louise Roe.
