Britney Spears and Katy Perry met at the premiere of "Smurfs 2." Perry, who voices Smurfette, also "secretly" collaborated on "Ooh La La," Spears' track for the film, presumably adding some "oohs" and "las."
They are now officially best friends.
Okay, no BFF press releases have been made, but they are going on a friend date.
Now, we can only hope they will release a single together after waking up in Vegas.
