A US basketballer better known as member of the Kardashian clan is fighting for his life in a Las Vegas hospital.

TMZ is reporting Lamar Odom was found unconscious at a Nevada brothel following several days of partying with girls.

Odom married Khloe Kardashian in 2009 and featured in that family's reality show and a spin-off.

She filed for divorce two years ago following his arrest for drink driving.
