Rihanna is known for her dedication to her fans and it seems that extends to cash handouts.  The 'Diamonds' singer made sure she was the most generous tipper while partying in Hollywood last week handing her waiter a $200 tip.

The singer was out enjoying herself at the Laugh Factory comedy club with her friends having fun and downing drinks according. Clearly in a good mood the 24 year-old decided to offer the waiter the biggest tip of his life when the bill arrived and despite being just $80 handed over $200 to him.

She asked the waiter what his biggest tip was, to which he replied $100, causing the star to hand over the wad say, according to sources: "Now I'm your biggest tip."
