Khloe Kardashian arrives for Kendall's 20th birthday party with Kris Jenner

The 31-year-old reality TV star looked forlorn and held onto her mother Kris Jenner as she arrived at The Nice Guy restaurant in Los Angeles on Monday night (02.11.15) to celebrate her younger half-sibling reaching her twenties.

Khloe has barely left her previously estranged husband's side since he fell into a coma after a drug and alcohol binge while partying at a Nevada brothel last month.

While the pair are no longer together, Khloe withdrew their divorce before it was finalised so she was able to make medical decisions on Lamar's behalf and since waking from his coma the basketball player has vowed to get better for the sake of his wife.

Most members of the Kardashian family were in attendance at the private party at the exclusive LA nightspot where guests were served cocktails and champagne.

As well as Kendall - whose birthday is today (03.11.15) - Kris and Khloe, Kylie Jenner and Kourtney Kardashian were also present as well as Kim and her husband Kanye West.

Kim - who is due to give birth to a baby boy this month - posted an adorable photograph of her kissing her spouse along with the caption "Mom & Dad turned up!"

Several of the model's famous friends also partied with the family, including Justin Bieber and Gigi Hadid, while Kylie's boyfriend Tyga accompanied her.

Kendall and Kylie posed for a number of selfies throughout the fun-filled night.
