Prince was rushed to the hospital today after his private jet made an emergency landing in Moline, IL, TMZ reports. According to the publication, the plane landed at the Quad City International Airport around 1AM and the 57-year-old musician was brought to a nearby hospital. The nature of the emergency is unclear, and the story is still developing.

UPDATE: A rep tells TMZ that Prince has been fighting a flu for several weeks. While the singer managed to go through with a performance at Atlanta’s Fox Theater last night, he felt “considerably worse” on the plane ride from Atlanta, necessitating the sudden hospital visit. He was treated and released after a few hours and is now resting at home.
