Lil Wayne was forced to cancel a gig in Las Vegas last night after being hospitalised after suffering several seizures.

The New Orleans rapper is epileptic and has been hospitalised in the past for the same reason, but was found unconscious in his Chicago hotel room on Sunday afternoon.

He was taken to hospital where he suffered another seizure and his current condition is not known.

The 34-year-old has spoken about his epilepsy in the past, after spending a week in intensive care in 2013 after a bout of seizures.  'This isn’t my first, second, third, fourth, fifth, sixth, seventh seizure. I’ve had a bunch of seizures; y’all just never hear about it," he later said. "This time it got real bad because I got three of ’em in a row, and on the third one, my heart rate went down to, like, 30 percent. Basically, I could’ve died soon. That’s why it was so serious."
