Rihanna is feeling fine after a brief hospital stay Monday night. People.com reports the 22-year-old checked herself into a private clinic after a concert performance in Zurich, Switzerland.

Her rep said the singer ``had an injured rib and went to have it looked at to be sure it was nothing serious, and it wasn't.'' Rihanna continued the European portion of her Last Girl on Earth tour Tuesday night with a concert in Lyon, France.

She is expected to perform in Marseille on Wednesday.
