"The proudest moment of my life was bringing you into the world. Even though it didn't happen the way we imagined, you are everything we could have hoped for and so much more," Kats wrote.

The new mum then shared the special way she decided on her baby girl's name, adding that she was named after "one of the most prolific Greek songs of all time.

"Earlier this year, James and I were in our villa in Bali when he played this song. I recognised it immediately and its lyrics about strength and resilience; a tribute to someone who stands out, someone real, strong, and unforgettable.. but I never knew the name of it.
