Rihanna may or may not have been drunk in this concert video

Are the wheels starting to come off for Rihanna? This video shows the singer at a Kings of Leon concert at the Heineken Open’er Festival in Gdynia, Poland looking a bit off her game. Then again Rihanna has been known to frequent bars and sing horrible karaoke, plus she slammed back more than a few in her Rihanna 777 documentary so it wouldn’t be a shock if Ri-Ri had one too many at an event sponsored by Heineken, would it?
