Kim Kardashian has unveiled what husband Kanye West got her for her birthday.

Kim, who recently turned 40, received a hologram of her late dad, Robert Kardashian Snr.

Lawyer Robert Snr died in September 2003, just two months after being diagnosed with esophageal cancer.

Sharing a video of the hologram, Kim penned on Twitter: "For my birthday, Kanye got me the most thoughtful gift of a lifetime. A special surprise from heaven. A hologram of my dad.

"It is so lifelike! We watched it over and over, filled with emotion."

The hologram tells Kim: "Happy birthday, Kimberly! You're 40 and all grown up. You look beautiful and just like when you were a little girl.

"I watch over you, your sisters and brother, and all your kids every day. Sometimes I drop hints that I'm around, like when you hear someone make a big pee fee, or when you make a big pee fee.

"Remember when I would drive you to school in my tiny Mercedes every day and we'd listen to this song together?"

Music begins to play, and the hologram of Robert Snr starts to dance.

"I am so proud of the woman that you've become," he adds, "and all that you've accomplished.

"It's a long and hard road, but it's worth it. I'm with you every step of the way.

"The way that you're connecting with our roots and supporting Armenia means so much to me. You are a proud Armenian, and I am a proud Armenian father.
