The former Made in Chelsea star gave birth to the pair’s first daughter, Sienna, last year.
And they now have even more to be excited about as Millie Mackintosh, 31, is expecting another little one who is due to be born later this year.
Today, the couple gave another update to their fans as they posted a video online of their gender reveal.
In the clip, they can be seen standing opposite each other as Millie holds up a black balloon with question marks.
Hugo Taylor, 35, moments later popped the balloon, unleashing a stream of pink confetti, confirming they were due to welcome another baby daughter.
Captioned next to the video which appears on Millie’s Instagram page are the cryptic words: “Girl or Boy……? Wait for it!!”
She went on to explain more about why the moment was so special to them.
Millie shared: “We were away with family a few weeks ago when the results arrived and I got my mum to organise a gender reveal balloon, we found out with Sienna over the phone and it was so special to make a moment of it!
“We are delighted and now even more excited about our new arrival.”
Hugo made his delight clear below his wife’s adorable post: “Very happy Papa right here Xx.”
Millie’s long-term friend and former co-star Rosie Fortescue also commented a stream of love heart emojis upon the news.
It comes just a few days after the pair celebrated their third wedding anniversary together.
The pair first got together in their Made in Chelsea days before both went on to have other relationships.
However, they ended up reuniting years later and married in 2018, two years after Millie split from her previous husband – Professor Green.
Millie shared a series of throwback snaps from their gorgeous wedding day to mark the occasion.
She penned: “Happy Anniversary my love @Hugotaylorlondon! I am so grateful everyday for the person you are and feel so lucky to live life by your side.
“You are the kindest man I know, I feel so loved by you and I’m so proud of the family we are creating. My moon and stars forever.”
