Kourtney Kardashian's baby son Mason reminds her of her late father.

The socialite and TV star - who has the five-month-old baby with her boyfriend Scott Disick - admits the tot is identical to her dad Robert Kardashian, who passed away in 2003 from cancer, in both looks and spirit.

She said: "The first thing people say when they meet Mason is that he is like my brother Rob and my dad's twin. He really does look so much like them - but to me he is totally his own handsome little self.

"Still, it's more than his looks that remind me of my dad - even Mason's energy reminds me of him. Mason is very mellow, calm, peaceful and happy. He's such a funny little boy who is always laughing and smiling.

Though the resemblance is a heart-warming reminder for Kourtney, it is tinged with sadness as Mason will never meet his Grandfather.

She added in her blog on People.com: "I do wish that my father and Mason had gotten to meet each other, but I know my dad is looking down on us and really does know Mason well."
