Rihanna is a party machine!
Hours after rocking the stage at the Brit Awards and winning the honor of International Female Solo Artist, our Barbadian beauty celebrated at the Mahiki club in London.
Although she created quite the stir, the 24-year-old pop sensation was prepared for all the flashing lights, as she wore vintage inspired light blue glasses.
As she exited the club she also had an extra accessory.
Rihanna had a peculiar looking mystery mark showing on her neck!
Now were not exactly sure what it is, or where it came from, however lets not forget RiRi is a good girl gone bad!
