Lil Wayne is in stable condition after suffering what his publicist describes as "two minor seizures".
TMZ has reported that the rapper's private jet was forced to make two emergency landings at an Omaha airport after he experienced the seizures on Monday afternoon and was taken to a hospital.
Dennis Messina, an operations supervisor at Omaha's Eppley Airfield, tells the Associated Press that a plane landed around 2.40pm due to a medical emergency, but that treatment was refused.
The plane refuelled and was just taking off when the pilot declared another medical emergency and returned to the airport.
Messina could not confirm that Lil Wayne was on the plane.
Derek Sherron, publicity director of the Chamber Group, says the rapper "thanks his fans for their everlasting support, prayers and well wishes".
