The former star of The City flaunted her lean and toned body in a floral bikini as she cooled off in the sea at South Beach.
It's the second time the 26-year-old has enjoyed a day by the seaside during her visit to the city - she was spotted frolicking on the shore in a white bikini over the weekend.

The star is now working with personal trainer John Damon, who puts her through what she describes as 'crazy bootcamp-type workouts'.
And she now tries to incorporate fitness into her everyday routine and even does exercise to get her ready for a night out.
'Push-ups get me pumped,' she told People magazine last week. 'I’ll do them before we go out at night.'

She is clearly thrilled with the outcome of her efforts and has posted several pictures on her website where she flexes her 'guns' - also known as muscly biceps.
Whitney is in town for Mercedes Benz Fashion Week SWIM 2012, where she has attended several catwalk shows.
She is currently working on the Spring 2012 collection for her line Whitney Eve and she also has a lower-priced line in the works.
