Lamar Odom is reportedly 'fighting for his life' after being found unconscious in a Las Vegas brothel.

According to TMZ, the former NBA player and soon to be ex husband of Khloe Kardashian 'fell into unconsciousness' at Love Ranch in Pahrump on Tuesday, having arrived three days prior.

An ambulance was called which is said to have taken him to a local emergency services, after which he was then transferred to a Las Vegas hospital.

Owner Dennis Hof says it looked as though Lamar had taken too much 'herbal viagra'.

Khloe and Lamar's divorce was finalised earlier this year, though Khloe is thought to 'currently be by his side' since hearing the news.

Lamar's former team mateKobe Bryant is also reported to have left his own basketball game to rush to the hospital where Lamar lays in a coma.
