The 32-year-old television personality - who first filed for a divorce from the 37-year-old retired professional basketball player in 2013 after four years of marriage - had her divorce finalised last year and has now decided to update her passport with her ex-husband's name removed from her identification, according to TMZ.

The 'Keeping Up With the Kardashians' star has celebrated the news with her family on Thursday evening (09.02.17) with a cake iced with a mock copy of her new official document.

And the golden-haired beauty's older sister, Kim Kardashian, 36, documented the party on social media.

Speaking in a clip on Snapchat, which saw the raven-haired beauty pan to the tasty treat, she said: "Look what Khloe's assistants got for her because she got a new passport.

"Without her old last name. It's her new last name and look at the weight you guys. Can you get skinny bitch as your weight? How cute is this cake you guys?"

Instead of detailing the 'Strong Looks Better Naked' author's current home address it listed "Freedom Lane" as her residence and weight as "skinny b***h" following her recent rapid weight loss.

Speaking about the descriptions on the edible passport on Twitter, Kim wrote: "It says Freedom Lane! Not her real address! I did not just show Khloe's address on my snapchat! It says Freedom Lane people!!! It's a joke! But Khloe's real weight is really 'Skinny Bitch' (sic)."

Although Khloé - who is currently dating Tristan Thompson, 25 - put off signing the court documents when Lamar was hospitalised in October 2015 after being found unconscious in a brothel in Nevada, the pair proceeded with the divorce, which was finalised in October 2016, and they are believed to still be friends.

Speaking previously, a source said: "There will always be a deep affection there for one another, but both of them have moved on. This divorce provides a natural end to that chapter in their life."
