Rihanna: Fans First, Party Later

Rihanna dons a cute Stella McCartney dress while heading to her afterparty at Greenhouse in New York City on Thursday (August 12).

The 22-year-old Barbadian singer had just performed for a sold out crowd at Madison Square Garden. This was Riri‘s first major concert at the Garden where she was joined by Ke$ha who helped open her show.

Ke$ha recently opened up about what it’s like working with Rihanna.

“It’s amazing! She’s just a badass,” Ke$ha told MTV. “I saw her yesterday, and she spanked me – always keeping me on my toes. She’s the sickest.”
