Elizabeth Hurley sent temperatures racing in a skimpy colourful bikini as she wished her friend a happy birthday as they wore matching two-pieces. 

The actress, 59, flaunted her washboard abs as she took to her Instagram on Thursday to share a stunning snap with her friend of 32 years, Ceila Wise.

They sported  blue, pink and purple triangle bikini tops and matching bottoms from Elizabeth's own collection, Elizabeth Hurley Beach.

To accessorise, the pair wore some oversized tinted sunglasses as they soaked up some sun on the beach. 

Elizabeth, who clung to a bright blue beach wrap, was the epitome of chic as she slicked her golden brown tresses into a middle-parted bun. 

Ceila looked incredible as she left her raven tresses to flow freely in the wind. 

Her lovely birthday snap comes after Elizabeth hinted at how she stays looking so good as she revealed her approach to diet and exercise.

She said that she has 'pretty simple' tastes and admitted she 'didn’t really know the difference between ultra-processed food and processed food until quite recently'.

However, the mother-of-one added that she 'always watched what I eat, since for ever', recalling checking food labels as a teen as she never wanted to consume highly processed foods.

Speaking to The Telegraph, she described her regime as 'very normal', and said she doesn't drink 'weird green juices or anything like that'.

Since learning more about processed foods, Elizabeth has ditched pre-packaged sandwiches, and instead, eats foods like roast chicken with mashed potatoes and vegetables.

She said her workout style is also simple, with her choosing to skip the gym in favour of being generally active, and admits that she rarely sits still.

She added: 'We have a rule in our house that no one’s allowed to put the TV on till 6pm, so nobody sits around until leading up to supper.

'But I do a lot of gardening… that’s quite bendy-downy, picking stuff up!'

Elizabeth and her 21-year-old son Damian recently came under fire from a professional psychotherapist over their controversial new movie together.

The film, Strictly Confidential, was written and directed by Damian and saw him direct his mother as she performed a lesbian sex scene.

The trailer for the movie raised eyebrows upon release, showing Elizabeth in a steamy scene with another actress.

While she claimed to feel 'liberated' by having a family member around to film the saucy scenes, Couples Therapy star Dr Jenn Mann criticised her actions.

According to the licensed marriage, family and child therapist, filming the scenes are a major boundary breach between parent and child, and she would advise against simulating sex in front of your child.

Jenn told TMZ she found the star's comments about the scenes being 'liberating,' 'bizarre' - and weren't aligned with a healthy parent-child dynamic.

Elizabeth previously told Access Hollywood she felt 'safe and looked after' shooting the film with her son. 

'It’s relaxing knowing someone’s behind the camera who looks out for you,' she explained, adding that was particularly important when filming this movie.

She continued: 'Because the things that his script needed me to do in this weren’t necessarily always done in movies many times before – but having him there meant I felt safe and looked after.

The Austin Powers star added: 'It’s kind of liberating to work with your family, I may do it again.' 

Damian agreed with his mother, telling the publication he didn't find the controversial scenes problematic. 

He said: 'We felt in our comfort zone, it’s very strange. I think, also, when you’re on an independent film, you have 18 days to shoot, every single second counts.

'You can’t sit around mulling scenes, thinking "What if?"
