It's just like old times for Katy Perry and Rihanna.
The "Roar" and "Who You Love" singer caught up with her one-time BFF last night at the pre-album release party for Perry's upcoming effort, Prism.
Looks like the one-time BFF is a BFF again ...
In a snapshot RiRi posted on Instagram, a beaming Katy Perry, who just released a duet with John Mayer, cozies up to the Barbados-bred beauty.
Rihanna's lips are pursed, playfully.
