Robert Kardashian - who is the father of Khloe and her siblings Kim, Kourtney, and Rob Kardashian, all of whom he had with his ex-wife Kris Jenner - passed away at the age of 59 after a short battle with oesophageal cancer in 2003.

And on the 14th anniversary of his death, his youngest daughter Khloe, 33, has posted a touching tribute to him on Instagram.

Posting a series of photos of her father with his brood, she wrote: "To the greatest of the great... miss you everyday! (sic)"

Khloe is the only one of the 'Keeping Up with the Kardashians' stars to have posted on social media in honour of Robert at the time of writing, however 36-year-old Kim did take to Twitter to retweet a number of tribute posts made by fan accounts.

Meanwhile, Khloe's post comes as she continues to take to social media amid rumours she's expecting her first child with her boyfriend Tristan Thompson, although she has not yet commented on the speculation herself.

The news was seemingly confirmed by Jeffrey C. Jenkins, an executive producer for Bunim/Murray Productions, who make her family's reality show, as he sent his congratulations via Instagram.

Sharing a picture of Khloe and Tristan, Jeffrey - who has worked on the show since it began 10 years ago - wrote: "Congrats my beautiful Khloe! You will be a great mom! God bless you all three! Mwah!!! @khloekardashian (sic)"

If the speculation is true, she will become a mother around the same time her older sister Kim - who already has four-year-old daughter North and 21-month-old son Saint with her husband Kanye West - welcomes her third child, which she is having via a surrogate mother after complications with her last two pregnancies.
