Kim Kardashian thinks about her father "every single day".

The 'Keeping Up with the Kardashians' star was devastated when Robert Kardashian died of cancer in 2003 and wishes he was still around to see all she has achieved.

She said: "I think about him every single day and I wish he were here to see everything going on.

"The peak of my life has been that I feel so blessed to have such an amazing family. The pit is the fact that my dad's not here to experience this all with us."

Kim is very close to her mother, Kris Jenner, who is also her manager, but admits the fact they are so alike means they often clash.

She said: "My mom and I vibe together on a business life. We're the most alike so that can mean a clash sometimes or extra-perfect."

Kim and her family's lives are documented in a number of reality TV shows and the brunette beauty admits they "really" open up on camera.

She added to InStyle magazine: "We really open ourselves up. The craziness, the arguments and the mistakes we make. We show a lot."
