Love Is Blind UK host Emma Willis is opening up about a recent health scare.

Willis, 49, shared via Instagram on Wednesday, April 23, that she underwent keyhole heart surgery in London after doctors discovered a hole in her heart.

“A few weeks ago, I had keyhole heart surgery, which feels very strange to write, and even stranger when I say it out loud. From investigations last year, to diagnosis and then surgery, they were absolutely incredible. As was @mattjwillis who never left my side 💕,” the television presenter said, thanking staff at London’s Royal Brompton Hospital and her husband and Love Is Blind UK cohost, Matt Willis.

Willis added, “Turns out, I’ve been pottering around for 48 years blissfully unaware I had a hole in my heart 🤯 isn’t it bonkers what’s happening in our bodies that we have no idea about…”

“What blows my mind even more is the wonders of modern medicine, and the spectacular people that save, fix and help us every single day. Can you imagine what it must feel like to have a pair of hand that can do that job?! They are the real superstar… ⭐️,” Willis, who also fronts The Voice UK, continued.

Willis went on to individually thank some of the medical staff who helped her overcome her health scare.

“A few of those people are Dr Alexander Lyon who investigated like a true super sleuth 🕵️‍♂️ Professor Wei Li, echocardiogram extraordinaire. Catrina, Carl and Tim who kept me at ease and humoured me when they were putting me to sleep,” she shared. “Marcus, Janet, Jayne, Hannah and Reem who monitored me at various points. Paulette, who was always up for a chat, gave great hugs, and loves a cinnamon slice as much as I do!”

Thanking her surgeon, Dr. Ee Ling Heng, Willis added: “She was recommended as ‘a spectacular pair of hands’, but my god, shes that and so much more. She has an ease and warmth that made me feel instantly comfortable all whilst being incredible professional and informative. I ask a million questions, and she answered them with the patience of a saint 😂 I knew as soon as we met that she was the woman I wanted poking around in my heart. Thank you Ee Ling, you’re one in a trillion ❤️.”

Emma and Matt Willis, also a singer with the U.K. band Busted, have been married since 2008. The couple shares three children.

Love Is Blind UK is expected to return for a second season on Netflix this year.
