Millie Mackintosh stripped down to a tiny bikini as she posed for a cheeky birthday selfie whilst on a family holiday.

The 36-year-old former Made In Chelsea star has been enjoying the sun with her loved ones over the last couple of days.

Taking to her Instagram on Sunday, Millie showed off her incredible physique in the mirror as she flaunted her toned abs.

Millie posed in the cream two-piece, wearing a fedora hat and carrying her wicker bag in one hand with her phone in the other.

She announced it is now officially Leo season in a photo dump on her socials, sharing snippets from their trip, although she hasn't shared the location.

'Vacation mode,' she wrote alongside the photo.

The doting mum-of-two, who is married to Hugo Taylor, enjoyed a quiet meal with her loved ones on the beach.

She was joined by her daughters Sienna and Aurelia as they sang happy birthday and watched their mum blow out candles.

Millie wrote: 'It’s Leo season. And just like that another 365 days older, wiser, and ready for what the universe has in store for me. Thank you for all the birthday love.' 

In recent days, Millie opened up about her dog helps keep her sober after she spent years battling alcohol issues.

She spoke openly about her issues with alcohol before going sober in 2022, and has since released a book about her struggles, entitled Bad Drunk.

And now in an interview with the Sunday Times, she has explained how owning her pug, Luna, as given her an additional focus.

She said: 'When you have a dog you’re not waking up with a hangover, you’re waking up and going for a walk along the river or meeting up with other dog owners.

'Having Luna helps me talk to people; I can be quite socially awkward. And I find when you’ve got a dog and another person’s got a dog, you just have something to talk about.'

Millie, who is married to former Made In Chelsea co-star Hugo Taylor and is a mother to two daughters, admitted she 'barely recognises the person she used to be' as she shared a 'drunken' throwback snap in a candid Instagram post.

She went sober more than two years ago following the realisation that she had become an 'angry' drunk.

As an MIC original, Millie's early scenes on the show often revolved around partying and drinking leading to flare-ups with fellow cast members which she has since claimed got in the way of her relationships.

Continuing to raise awareness of sobriety and how much her life has changed for the good since going alcohol free, Millie wrote: 'Now vs. Then.

'Looking back ten years, I barely recognise the person I used to be—drinking heavily, always hungover, and completely lost.

'I was stuck in a cycle of self-medicating, not realising that the change I so badly needed was waiting for me on the other side of discomfort.

'Choosing an alcohol-free life has been the best decision I’ve ever made. It’s the ultimate life hack—realising that I have the power to say no.

'Not because I have to, but because I get to. Sobriety isn’t a sacrifice; it’s a privilege, a gift I’ve given to myself, and one I’ll never take for granted.

'The journey from bad drunk to alcohol-free has been the most transformative thing I’ve ever done. And hearing from so many of you who are on this path too means so much.

'Your messages about my book and your own experiences remind me why this conversation is so important.

'If you’re navigating this too, know that you’re not alone—we’re in this together. How are you feeling about your own journey right now? Let’s chat. ✨'

Millie decided to go and see a sober coach, who helped her and has now steered clear of booze for more than two years.
