Millie Mackinitosh has revealed the secret to her incredible abs after showcasing her taut stomach at Sunday night's TV BAFTAs. 

Taking to Instagram on Tuesday, the former Made In Chelsea star, 36, admitted that she sought help to achieve her envy-inducing stomach, which she showcased in a lemon yellow crop top and mermaid-tail skirt. 

The star is mother to Sienna, six, and Aurelia, four, with ex-husband Hugo Taylor and candidly admitted having her incredible physique is 'not effortless after two kids'. 

She detailed that despite 'eating well and exercising most days' she utilised Quantum RF, a skin-tightening treatment, as well as Emsculpt Neo - which is a non-invasive body contouring treatment - to help firm up her taut stomach. 

She wrote: 'Thank you for all your lovely comments about my BAFTA outfit! I have had a lot of questions about my abs and my workout routine....

'The truth is that they are not effortless, especially after 2 kids! I eat well and exercise most days but I wanted a little extra help so tried @quantum RF about 3 months ago with @drandresbello @sadaf_jaffari’s clinic...

'It’s a minimally invasive treatment using radio-frequency energy to tighten & contour the skin. The full results are after 1 year but I am really starting to see a difference now and it really helped with the area of skin above my C section scar...

'As always I want to be transparent about my tweaks and not gate keep! I also love @emsculptneo for toning in a way that no amount of sit ups can! Next I want to try the Co2 laser to target the texture of the skin. #AD/PR”'.

She thanked plastic surgeon Andres Bello and surgeon and aesthetician Sadaf Jaffari for assisting in her tweakments.

Millie, who announced her split from second husband Hugo in March, has spoken in the past about struggling with her post-baby image. 

Speaking after Sienna's arrival, she said: 'I did feel self-conscious when I went out and wouldn’t want anything to be tight to my tummy. I did struggle looking in the mirror for the first three months...

'I did feel a bit ashamed of my postpartum body. And it’s kind of sad that I felt that…It feels good to admit that... It definitely won’t go back to being exactly the same as before and I’m okay with that…I feel more womanly, and I’m really loving it.'

At the BAFTAs, Hugo's best friend Spencer Matthews sensationally blanked his former Made in Chelsea co-star, Millie.

The father-of-three was best man at Millie's wedding to Hugo in 2018 but he completely ignored her on Sunday, as he greeted those around her in the queue for pictures on the red carpet.

Standing with his pregnant wife, Vogue Williams, the 37-year-old momentarily left her to greet the BBC journalist, Anita Rani, who interviewed him two years ago for a Christmas Special.   

The star walked straight past his former castmate with whom he shared a screen for two years and she appeared visibly put out by the snub, turning away from him.

Despite having grown up in a privileged world where politeness is all, Spencer skipped out on his manners and completely ignored the mother-of-two who he has known for well over a decade.

Millie and Spencer have a long and chequered past with many explosive rows on the E4 series on one occasion, in 2012, the influencer slapped him for cheating on her friend, Louise Thompson.
