Rosie Huntington-Whiteley and Jason Statham provided a fresh bout of January-detox inspiration as they both paraded their impeccably-toned figures while enjoying a romantic getaway in Phuket, Thailand, on Tuesday.

The British supermodel and her actor boyfriend showed no sign of overindulgence as they stripped down to their swimwear smalls to enjoy a day out on the Amanpuri coast in the south of the country.

Rosie, 28, showcased her superbly slim bikini body as she slipped into a skimpy two-piece which comprised patterned bottoms and a matching bandeau-style top.

The statuesque catwalk queen showed off her endless stems and her taut tummy as she sauntered around the idyllic setting alongside her partner of five years.

Despite being off-duty, Rosie’s figure looked gym-honed and her bare complexion looked completely flawless from head-to-toe.

The Plymouth-born fashion darling relished a rare opportunity to work a low-maintenance look, ditching every inch of make-up and favouring a messy updo.
