Influenza makes no special treatment and strikes celebrities equally.

Flu’s last victim is Janet Jackson, who was forced to make a visit to the hospital to alleviate her condition. The artist experienced “shortness of breath,” as “Us Weekly” reported the first. The singer checked in shortly at the Cedars-Sinai Medical Center late on Monday night to receive proper medical attention.

“She's been battling this flu like everyone else,” “E! News” quoted Jackson’s rep, Patti Webster, as saying.

But despite her short stay at the hospital, the 41-year old artist is forced to cancel her appearance on this weekend’s “Saturday Night Live,” her publicist said. Jackson was a eagerly waited guest on the show, due to promote her freshly released album “Discipline.”

The recent material launched by the artist is a success, at least until now. The release debuted atop the hottest “Billboard” album charts the last week. This is far from the first success of this kind for the singer, Jackson managing to hit the hottest spot of the album charts previously for other five times. Janet Jackson is also preparing a grant tour to promote the album later this year.

The artist is also planning for another surprise release by the end of this year. Jackson, helped by her nutritionist, is due to launch a book on weight loss. The book, whose name hasn’t yet been decided, will also disclose the singer’s history of being an “emotional eater.”
