RIHANNA FINE AFTER HOSPITAL STAY

Rihanna okay after....



a brief hospitalization Monday night in Zurich, Switzerland.

After performing in concert, the 22-year-old singer was taken to a private clinic because she had an injured rib.

RiRi "went to have it looked at to be sure it was nothing serious, and it wasn't," her rep said. "All is OK and the tour is going great."

The singer continued the European leg of her "Last Girl on Earth" tour Tuesday night with a show in Lyon, France. She is also expected to perform Wednesday in Marseille.

GV Says: How did she injury her rib???? Can't say that's something that happens in the normal course of life. (giving this story the side-eye)
