Rihanna made her appearance at Germany's version of the Grammys, the 2010 Echo Awards a memorable one.

The 'Rated R' singer got her butt tickled by a Transformer during her performance of "Rude Boy"

She playfully teased the robots throughout and gyrated her hips while touching herself several times.

I must say, I enjoy her live shows.
