Singer R. Kelly is suffering from a mysterious "health emergency", according to TMZ.
A representative says Kelly has officially postponed tonight's New York book launch event "due to a health emergency that has sidelined Mr. Kelly in Chicago."
A statement explaining the nature of his illness was released:
"While on his way to New York this morning (06-27-12) to celebrate the publication of his long-awaited memoir “SoulaCoaster,” multi-platinum R&B superstar R. Kelly was taken ill and had to return to Chicago for medical treatment. Initial indications are that he is suffering from complications from surgery he had last year to treat an abscess on his vocal cords. As a result, Kelly has had to cancel appearances on “The Jimmy Fallon Show” and NBC’s “Today” as well as a book party that was being held in his honor. It is unclear how long Kelly may be sidelined."
Kelly is dropping a memoir called “Soulacoaster: The Diary of Me,” on June 28, and a new album, “Write Me Back,” on June 26th.
