The first image shows Kathryn and Josh share quite the endearing moment as they lovingly kiss one another while the Inherent Vice actress is seen rocking a pair of black sunglasses and a diamond pearl necklace.

Kathryn’s follow-up image in the gallery then sees the blonde beauty flaunting her big baby bump while seemingly posing at the ocean in stripy green pants and a white top.

Given that she’s 40 weeks pregnant, it seems Kathryn seems well aware that the day of her baby’s birth could very well be right around the corner.

The exciting news comes just days after Josh had posted a video on the same social media platform, showing his wife listening to music as she attempts to ‘dance that baby out.’

‘Taking this video actually brought tears to my eyes. I have the greatest soul mate you can have,’ he wrote.

‘Bouts of darkness hit and we/she powers through it. Then moments of the power of this miracle hit and inevitable moves come.
