Spiritual Kim Kardashian goes to night vigil for brother-in-law Lamar Odom'

While this weekend was supposed to be a time to celebrate new life for Kim Kardashian, the expecting mum-of-one will instead be among family willing for her brother-in-law's survival.

Kim, 34, has reportedly cancelled her Beverly Hills baby shower at the last minute to support sister  as the Kardashians hold vigil for Khloe's estranged husband Lamar Odom, 35, in Las Vegas.

Pregnant Kim, who already has two-year-old daughter North with husband Kanye West, was expected to throw the celebration this weekend but was seen arriving at Nevada's Sunrise Hospital on Wednesday following the former NBA player's collapse at a legal brothel.

A source told E! News that family is currently Kim's priority, explaining: 'She's totally focused on being there for Khloé right now.'

Khloe and Lamar separated nearly two years ago following four years of marriage and even though they recently signed court papers together, their divorce is still said to be 'pending'.

Kim's big sister Khloe is now said to be making his medical decisions as his legal spouse while he fights for his life following suspected consumption of 10 herbal Viagra.
