Millie Mackintosh unveils bump and announces she is expecting a second baby

Her social media feed is full of adorable pictures with her one-year-old daughter Sienna – and now Millie Mackintosh has announced she is expecting a second baby.

In a post on Instagram, the former reality TV star, 31, showed off her growing bump, while holding her little girl in her arms, as she revealed her second child with husband Hugo Taylor is "due later this year".

Captioning the image – in which she is wearing a form-fitting pink one-piece – she wrote: "We are so excited to announce that Sienna is going to be a big sister!

"I couldn’t keep this to myself for much longer and I’m running out of ways to hide my bump! Baby 2 is due later this year."

The news delighted her fans, who left more than 134,000 'likes' and over a thousand congratulatory messages.

Jamie Oliver's wife Jools commented: "That’s so exciting congratulations."

Fellow Made In Chelsea star Binky Felstead – who recently gave birth to her second child – wrote: "So exciting!!!"

The Saturdays band member Mollie King shared: "Congratulations!!"

Mackintosh wed 35-year-old Hugo Taylor – who also appeared on MIC – in 2018, after her three-year marriage to rapper Professor Green ended in 2016.

In April, she appeared on the cover of Women's Health, opening up to the magazine about her relationship with her post-baby body.

The star shared how her confidence about how she looked plummeted in the weeks after she gave birth, explaining: "It was honestly quite hard to see my body after a baby."

She noted: "And I think it is for a lot of women. It can really feel like a shock and something that’s hard to love, maybe – and hard to feel good about."

However, Mackintosh said she had experienced "crazy stupid love" when her firstborn arrived, in what was the middle of the first UK lockdown.

She added: "Your life is turned upside down. [I’ve] just never felt the love like it – it’s crazy how much your heart opens."
