Contrary to popular belief, Rihanna isn't always in party mode.
Rihanna spent time at the EIF's Women's Cancer Research Benefit event last night.
To liven up the event, Rihanna hopped on stage and performed a few of her songs. RiRi even hopped in the crowd and let Sheryl Crow join in on all the action.
Besides raising money for cancer research, Rihanna is also shooting the visuals for her Talk That Talk track "Where Have You Been."
RiRi's been leaking video stills of her on the set, teasing fans that she'll be releasing the video very soon.
The official "Where Have You Been" isn't on the 'net yet, but you can get your daily dose of Rihanna in the gallery above!
