“Our beautiful baby boy made his grand entrance into the world at 11:19 AM on September 26th 2020 after a short and intense six hours. 3530 grams and 52 cm,” wrote Henson on Instagram.

“The birth was the most powerful, life changing, empowering thing I’ve ever done in my entire life. We are all doing well and settling in at home as three!”

In a separate post, Björnsson also discussed Henson’s “extremely hard” labour.

“After an extremely hard 2 hours and 19 mins of pushing our healthy, strong, beautiful boy arrived weighing [7 pounds 7 oz, 20.4 inches long],” he said.

“To finish the most beautiful, awe inspiring labour was the most wonderful phone call to my daughter to introduce her to her new little brother.”

Björnsson also shares daughter, Theresa Líf, with his ex-girlfriend Thelma Björk Steimann.

The athlete previously shared a post on Instagram revealing there was a chance he could have missed the birth of his son due to coronavirus quarantine.

At the time, Björnsson was in isolation and being tested for COVID-19 after coming into contact with someone who later tested positive.
