Kim Kardashian West has cancelled her baby shower after Lamar Odom's collapse.

The reality TV star's former brother-in-law was rushed to hospital after being found unconscious at the Love Ranch brothel in Nevada earlier this week and the Kardashian clan, including his ex Khloe, have rushed to his bedside, where he remains in a critical condition.

Kim, who is pregnant with her second child, was due to have a 'Troop Beverly Hills' themed shower at the weekend, at her friend Allison Azoff's Beverly Hills' estate.

It is the same place where Khloe and Lamar's wedding was held in September 2009.

However, Kim has called off the party in order to be with her sister by Lamar's hospital bedside, according to E! News.

Khloe is making medical decisions for Lamar as although she filed for divorce in 2013 amid claims he'd cheated on her and was addicted to crack cocaine, there's said to be a backlog in the family law courts.

The 'Keeping Up With the Kardashians' star delayed her divorce for a year and a half as she tried to save her marriage to Lamar - with whom she tied the knot after a month of dating - and although they both eventually signed their final divorce documents the backlog means it won't be completed for at least two months, TMZ has reported.

Lamar - who is also believed to have taken cocaine and ''virtually every drug imaginable'' - was also taking herbal Viagra pills during his four-day stay.
