Flynn, whom Kerr describes as her "little ray of sunshine", was born on January 6 and weighed 4.42 kilograms. He is Kerr's first child.

Bloom is credited with taking the photo of the pair, which was released on the model's website. It shows Kerr breastfeeding the baby.

In the post she also reveals details of the birth.

"I gave birth to him naturally; without any pain medication and it was a long, arduous and difficult labour, but Orlando was with me the whole time supporting and guiding me through it. I could not have done it without him," she writes.
