Katy Perry and Rihanna Party Together At New York Club (PHOTOS)
The singers were both on hand to celebrate with Walshy Fire at his birthday soiree at 1Oak.
One photo shows Perry and Rihanna on either side of the birthday boy (see right and below).
In that pic, you also see that Perry stuffed her cell phone into her bra. Nice touch.
A good time was had by all.
