G4L.

Rihanna and Katy Perry are RIunited again!

I would love to witness their friendship in person.

A bubbly personality meets a Bajan princess.

The girls linked up on Monday night in downtown New York City at the pre-album release party for Perry's upcoming effort, Prism, just days after the album's lead single, "Roar," which was leaked online.

In a snapshot that RiRi posted on Instagram, a beaming Perry cozies up to the Barbadian beauty, while Rihanna, lips pursed and eyes shut, strikes a playful pose. (above)

"She. X She. #KatyAnna #RIHunited," the "Nobody's Business" songbird was the caption of her picture.

Perry recently gushed to Elle U.K. about her friendship with Rihanna. "I love her and every time I see her, I'm reminded of the light that she has," John Mayer's gal-pal said. "There's a lot of dark in this business."

Still, Perry appeared to express her concern about the company that her friend keeps.

"I know a lot of people out there with the most detrimental entourages—they are the root of their demise," she said, declining to name-check anyone specifically. "It's really unfortunate but you can't save these people. My days of celebrity saving are over."

I am glad that they got back to hanging out and enjoying each others company again. Stay tuned.

They are truly G4L (GIRLS 4 LIFE)!!!
