VIDEO:Shakira was robbed - during a concert in Mexico!

Shakira was robbed while in the middle of a performance -- and the whole incident was caught on camera.

The Colombian pop star was shaking hands with fans during a show in Monterrey, Mexico, when a ring was taken right off her finger by a concertgoer.

The video of the incident clearly shows Shakira's confused reaction to losing her ring, but -- always the professional -- she continued her performance without delay.

There's no word on the price of the stolen ring or where security was when the incident occurred.
