Kim Kardashian releases first picture of baby Saint to mark late father Robert Kardashian's 72nd birthday

Kim Kardashian released the first picture of her son Saint West to mark her late father Robert Kardashian's birthday on Monday.

Writing a tribute to the lawyer on her website KimKardashianWest.com the 35-year-old explained: 'Today is my dad's birthday.

'I know there's nothing more in the world he would have wanted than to meet his grandchildren. So I wanted to share this pic of Saint with you all.'

The first picture: Saint West is seen sleeping in an image released by Kim Kardashian

The two-month-old is seen dressed in a simple cotton vest, arms outstretched beside his head as he sleeps soundly on a white sheet. 

February 22 would have been the 72nd birthday of the grandfather Saint will never get to meet - OJ Simpson's lawyer Robert Kardashian - and it is obviously a date Kim wanted to remember.
