Rihanna 'Okay' After Being Hospitalized for Injured Rib

Rihanna is feeling fine after being briefly hospitalized Monday night.

The singer, 22, who was taken to a private clinic after performing a concert in Zurich, Switzerland, "had an injured rib and went to have it looked at to be sure it was nothing serious, and it wasn't," her rep tells PEOPLE.

Rihanna continued the European leg of her "Last Girl on Earth" tour Tuesday night with a concert in Lyon, France, and is expected to play in Marseille on Wednesday, according to reports.

Adds the rep, "All is okay and the tour is going great."

Rihanna plans to kick off her North American tour in Seattle with pop star Ke$ha in July.
