Millie Mackintosh steps out with newborn Aurelia Violet for first time… hours after she and husband Hugo Taylor announced birth of second daughter

Millie Mackintosh stepped out in London with her newborn daughter Aurelia Violet on Tuesday, hours after announcing the birth of her and her husband Hugo Taylor's second child.

The former Made In Chelsea star, 32, bundled up in a cosy white coat, bobble beanie and grey tracksuit bottoms as she pushed little Aurelia in a black pram.

Hours earlier, Millie took to Instagram to reveal she had given birth to a baby girl by posting a photo of herself cradling Violet in her arms in a hospital bed as her husband wrapped an affectionate arm around her.

Enjoying a stroll in the capital on Tuesday, Millie was joined by her nanny, who pushed her eldest daughter, 18-month-old Sienna, in a pram.

Millie wore her hair loose and looked radiant as she enjoyed some quality time with her two children.

She teamed her outfit with a stylish pair of boots and clutched a cup of coffee in her right hand.

Alongside a sweet photo of herself, Hugo and Aurelia, Millie gushed on Tuesday: 'Welcome to the world Aurelia Violet Taylor!

'Our little bundle of joy arrived safe and sound and our hearts are bursting with love. I'm signing off for a bit to spend time with my family in our newborn bubble.'

Underneath Millie's announcement, Hugo - who Millie wed in 2018 - sweetly wrote: 'You are our families' hero! We (Aurelia, Sienna and I) love you so much [heart].'

The couple previously revealed they were set to welcome another daughter to the family with a sweet gender reveal, which they shared to Instagram in June.

The reality star has closely documented her pregnancy online as well as giving updates on what it is like to be expecting while looking after a young child.

Millie recently asked her followers for baby name advice, saying she and Hugo have been struggling to come up with a moniker that would 'compliment' Sienna's.

She penned: 'Choosing a name for your second child is totally different than naming your first. There are more factors to consider, you want the names to compliment each other, but still be strong and individual by themselves.

'We loved the name Sienna from the very start and were certain that was what she would be called.

'We want the new bubba to have a name that we love just as much, but it's proving tough! We have a couple of names on the table but any suggestions are welcome!'

Millie's devoted followers soon flooded the comments with gorgeous names including Ivy, Savannah, Florence, Elodie, Summer, Poppy, Amalie and Harriet.
