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.

“She. X She. #KatyAnna #RIHunited,” Rihanna captioned the photo, the first we’ve seen of the two of them – once seemingly inseparable – in some time.

The reason for their supposed rift? Chris Brown, who Rihanna very publicly reconciled with earlier this year … but who is once again out of the picture.

Perry reportedly cooled to the friendship after Rihanna took back Chris, who infamously assaulted her, though she never confirmed this publicly.

“I know a lot of people out there with the most detrimental entourages, they are the root of their demise,” Perry said this year (without naming Rihanna).

“It’s really unfortunate but you can’t save some people. My days of celebrity saving are over,” she added amid reports that they had a falling out over Breezy.

In any case, all is right with the world right now … particularly if they start going to strip clubs, making it rain and making out in future Instagram photos.
