Rosie Huntington-Whiteley's Teeny-Tiny String Bikini (PHOTOS)
Well, we can definitely see why Rosie Huntington-Whiteley was cast in Transformers!
The model-turned-actress showed off her flawless bikini body when she hit the beach in Mexico in a barely-there two-piece. Roaming around some ruins, Rosie chatted with a male friend and dipped her toes in the crystal blue waves.
Rosie is getting in a little R&R before she gears up for the big promo push for her feature film debut, Transformers: Dark Side of the Moon. Rosie was infamously cast to replace Megan Fox after the sultry actress ditched the hit film series.
