Former NBA star Lamar Odom in hospital after being found unconscious in Vegas brothel

Former NBA star Lamar Odom has been rushed to hospital after being found unconscious and "foaming" at the mouth in a Las Vegas brothel, police said.

Paramedics were called to the Love Ranch in Nevada after Odom, who was previously married to Khloe Kardashian, was found unresponsive.

Officials tried to airlift him to hospital but the 6ft 8in basketball player was reportedly too tall to fit in the helicopter, so he had to be driven by ambulance.

There is no further word on his condition but local media report he is 'fighting for his life'.

NBC News report that brothel's owner, Dennis Hof, claims Odom had taken large amounts of what he described as "herbal viagra" but no illegal drugs were found in the athletes' room.

"We called 911, and the 911 told my staff what to do: turn him over on his left side," Hof said. "There was this terrible foaming stuff coming out of him. He was throwing up, a little bit of blood."

Odom, who won two NBA championships with the Los Angeles Lakers, last played in the NBA in 2013.

The 35-year-old also found fame through his marriage to Khloe, who he married in a taped ceremony for the E! network in 2009.

But Khloe filed for divorce four years later citing irreconcilable differences.

Stars from the basketball world have been tweeting their messages of support to Odom.
