The actress flaunted her figure as she splashed about in the sea in Miami with her mum

Anne Hathaway has been snapped showing off her dramatic new look in a slinky bikini during a trip to the beach in Miami.

Having been given a break from filming in the UK, the actress decided to head home to the States and enjoyed a nice afternoon with her mum at the seaside.

She looked super toned as she strolled into the sea (while pretending to ignore the dozens of people staring at her, open mouthed) in simple a drawstring bikini and oversized aviator shades.

Anne was told to shave her head and lose just over a stone as part of her role on new movie Les Miserables.

The 29 year old plays a dying prostitute called Fantine in the iconic musical and was given less than a month to drop two dress sizes by the director.

Anne starting filming the tragic flick last month as a size ten, but was told to shed 16lb in 20 days to make her character’s death bed scenes more realistic.

Rather than eating the recommended dietary allowance of around 2,000 calories a day, Anne is consuming fewer than 500, so that by the end of filming, she will be an emaciated size six.

A film set source told our mate Clemmie at the Mirror: “Anne is playing a destitute factory worker-come-lady of the night.

“Unfortunately, she only has 15 to 20 days to lose as much weight as possible – up to a stone-and-a-half – because she’s been filming the scenes showing her fit and healthy, almost slightly chubby.

“It’s not ideal but, as with any high-budget movie, there are strict time constraints.

“Producers have assigned her a personal trainer and she is literally eating nothing more than a couple of apples a day, and some protein – mainly in the form of a shake.

“Anne knows the risk of such an extreme diet and will undergo weekly medicals to make sure everything is still functioning as it should do.”

The movie is based on the hit West End musical and also stars hunks Eddie Redmayne (FIT), Hugh Jackman and Russell Crowe. The cast began filming early this month.

It’s due to hit cinemas in December, so Anne’ll have time to get her beautiful curves back for the premiere.
