The 'Lollipop' hitmaker was rushed to Cedars-Sinai Medical Center in Los Angeles after allegedly suffering multiple seizures on the set of Minaj's new video, reported TMZ online.
Wayne was readmitted hours after he was released when his bodyguard found him lying unconscious in his room.
The 30-year-old, whose real name is Dwayne Carter Jr, was treated in the intensive care unit, and was visited by the American Idol judge, who spent an hour by her label boss' bedside.
