Watch out all Michael Jackson fans out there, Rihanna is taking on one of the late King of Pop's signature moves and it ain't pretty! During her concert in Hamburg, Germany, the R&B diva attempted the Moonwalk and let's just say that girlfriend didn't exactly bust a move, she butchered it!

Now we know why the "Umbrella" star keeps falling on stage and injuring herself on her European tour! During a performance of her song "Let Me," RiRi slipped and fell in her supa dupa high heels and glided toward the edge of the stage!

She better be careful. While the "Rude Boy" songstress tried to get up as fast as she could and with as much grace as possible, it was clear that she did not expect the fall to happen and was totally caught by surprise, oops!

Before that incident she was taken to a hospital in Switzerland for a broken rib. According to British tabloid The Sun, the "Rude Boy" songstress was taken to a nearby hospital and was treated for "a mystery ailment."

"Rihanna arrived at the accident and emergency unit. We're not going to give any details," the head of the clinic's corporate communications, Alenka Ambroz, told Swiss newspaper Blick according to The Sun. The Bajan beauty was reportedly released from the private clinic around 3AM and she was back on track, performing in front of a cheering crowd in France the following night.

Sounds like this pop star is in need of a holiday. But instead of taking a break, she attempts to break it down to MJ's Moonwalk, but the sexy songstress is far from mastering the King of Pop's master move! Dressed in a revealing white outfit and high heels, RiRi performs her hit "Don't Stop the Music" and all of a sudden turns around and starts doing the Moonwalk!

What could have been a highlight during Rihanna's show turned out to be a fiasco. Check out Rihanna's attempt to do the Moonwalk here and let us know what you think. Can Rihanna do the Moonwalk or should she stick to simpler dance moves?
