Kate Hudson, 47, shows off her toned form in a skimpy black bikini on family summer break to Greece

showed off her incredibly-toned figure in a tiny black bikini in a series of snaps shared to Instagram on Monday. 

The actress, 47, has jetted off to the Greek island of Skíathos with her fiancé , 40, and their seven-year-old daughter, Rani Rose and her son Bingham Bellamy, 14. 

Kate posed up a storm in the skimpy swimwear with the halterneck bikini top showcasing her abs. 

The family headed out on a boat trip from one of the 60+ crystal-clear beaches. One photo showed Kate and her teenage son relaxing on the deck. 

Other photos included Kate having a great time at dinner with her pals and a sweet hug. 

Kate captioned the post: 'My happy place'. Fans wrote: 'Stunning' and 'You look very calm and so happy'. 

Besides Rani, Kate also has son Ryder, 22, with ex-husband and The Black Crowes rocker Chris Robinson, 59. 

She shares her son Bingham with her former fiancé and Muse frontman Matt Bellamy, 48.

Kate is a well-known fan of sun and beach holidays, with Greece being a particular favourite.

The actress might be in her mid-40s, but she isn't daunted by the prospect of getting older.

The subject came up while she was reflecting on the recent praise that she's received for Song Sung Blue, which was inspired by the true story of Mike and Claire Sardina, a working-class couple from Milwaukee, Wisconsin who found fame as Lighting & Thunder, a Neil Diamond tribute act.

'It really does feel humbling,' Kate- who is the daughter of Goldie Hawn and singer Bill Hudson - told The Hollywood Reporter in January.

'But I was saying to my mum the other day, "People talk about age and I don't even think about it.' I don't think about time backwards. I don't long for anything behind me. I don't know if it's just my nature, but my mum's very similar."

And in spite of her own successes, Kate still has to fight for all of her film projects, insisting that nothing comes easy in the movie business.

The actress observed that Song Sung Blue, her biographical musical drama film, initially struggled to find support from movie studios.

'You realize that there's always an uphill battle in every choice that you really believe in and has to be made,' she said.

Kate is currently starring in the Netflix basketball comedy Running Point. She portrays Isla Gordon, who navigates the chaotic dramatics of running a family-owned sports dynasty while dealing with her havoc-causing brothers.

The series was recently renewed for a third season.
