Sydney Sweeney looks stunning as she strips off to a bikini to sunbathe in Florida

SYDNEY Sweeney showed off her toned figure as she stripped to a bikini in Florida.

The Anyone but You actress, 27, looked incredible in a purple floral patterned two-piece.

The White Lotus actress, who recently filmed a biopic portraying champion boxer Christy Martin, showed off her trim frame in the thong bikini.

The Hollywood star, who underwent a body transformation to bulk up for the movie, was seen enjoying some well-deserved down time at her huge $13 million waterfront mansion in the Florida Keys.

She wore her hair in a messy bun, a pair of designer sunglasses and opted for no makeup as she spent the day sunbathing.

Sydney has been taking the time to relax and enjoy some quality time with her fiance Jonathan Davino, 41, and close friends.

She appeared looked in good spirits as she soaked up some rays while lounging around on a sunbed.

The movie star was also seen chatting to a female friend - before cooling off by taking a dip in her swimming pool.

Sydney is best known for her critically-acclaimed roles in The White Lotus and Euphoria.

But the star has completely transformed her look for her latest role in gritty new biopic Black Bear.

In October, Sydney looked unrecognisable in shots taken on the set of the film, which tells the story of 90s superstar boxer Christy Salters-Martin.

Sydney swapped her long blonde hair for a shorter dark style that was held back from her face by a bandana.

Her favoured glamorous low-cut dresses were replaced by low-key T-shirt and zip-up hoody combinations.

Ben Foster was also snapped on set in his role as Jim Martin, Christy's abusive husband and trainer.

Christy took the boxing world by storm in the 90s, winning the WBC title and appearing on the cover of Sports Illustrated - the first female boxer to do so.

She was nicknamed The Coal Miner's Daughter after her father's job and became controversial promoter Don King's first female client when she joined his stable in 1993. 

Christy fought on the undercard of Mike Tyson's heavyweight world title clash with Brit fighter Frank Bruno and put on a masterclass that many say outshone the main event.

Tyson said in a new Netflix documentary: "I believe I was in jail and they were talking about "Coal Miner's Daughter", she's knocking out people, she's really exciting.

The Euphoria star has been hailed ''the sexiest woman in the world'' and recently made fans go wild after stripping naked in a bath.
