Harry Potter star Louis Cordice is set to become a dad for a fourth time.

The 36-year-old star - who played Slytherin student Blaise Zabin in the boy Wizard franchise - and his wife Natalie shared the exciting news that their daughters Isla, five, Rose, two, as well as Louis' son Kaise, nine, are going to have another sister on Instagram.

On Monday (09.03.26), Louis posted a picture of the ultrasound and a joyous Isla and Rose holding a "mummy to be sash" with the caption: "Soon we'll be welcoming another little girl into our family, and I honestly can't wait to meet her.

"In what feels like no time at all, Isla and Rose will have a baby sister to grow up with. They might not realise it yet, but they're going to be the best big sisters."

The actor - who appeared in Harry Potter and the Half-Blood Prince (2009) and Harry Potter and the Deathly Hallows, Parts 1 (2010) and 2 (2011) - then shared how "proud" he is of Natalie for carrying their bundles of joy.

Louis continued: "I also just want to say how proud I am of my beautiful wife. Watching her carry our babies and bring three incredible girls into this world is something I will never take for granted.

"I'm forever grateful to her for the amazing family we've built together.

"Not long now until we meet you, baby girl."

Louis and Natalie - who got married in June 2025 - were showered with congratulatory messages in the post comments section.

One person penned: "Congratulations Louis! Wishing you and your family much health and happiness. Much success in this new chapter of your lives. (sic)"

A second user typed: "Awww congrats guys!! And what lovely words you wrote about your beautiful family + wife (sic)."

And a third fan wrote: "Oh this is so great, congratulations to you and your lovely family. All the best to you all. (sic)"

Following Harry Potter, Louis quit acting and became a senior finance recruitment specialist.

Describing his new career, he is quoted by the Daily Mail as saying: "I specialise in building strong, high-performing finance teams by focusing on the unique needs of both clients and candidates.

"My approach goes beyond simply filling roles - it's about long-term, meaningful relationships and finding the right cultural fit."

However, the former child star still makes appearances at Harry Potter conventions across the world.

Previously speaking about the fan shows, Louis said: "I'm lucky to travel the world and get to go to conventions, compared to what we see now, meet Harry Potter fans that now have children."
