The 'Unfaithful' hitmaker was partying at a nightclub in Los Angeles when American Footballer Braylon Edwards and his teammates sent the expensive drink over to her table.

However, the 21-year-old singer refused to accept the gift because she had no idea who they were, Contactmusic reported.

"She didn't know who they were, so she sent it back," said a partygoer.

While Rihanna is gifted expensive drinks when she goes out, actor Kiefer Sutherland buys his fans a beverage.

The 'A Few Good Men' star bought all the customers a drink after he and some crew members of the hit US drama series '24' popped into a bar in California, after finishing a shoot at seven in the morning.
