What do you get when you put all of pop's biggest teen stars in one house for a sleepover? An amazing homemade music video, of course!
This is exactly what happened when Justin Bieber, Selena Gomez, Ashley Tisdale and pals went round to Carlos from Big Time Rush's house - and the result has got us already LOVING Carly Rae Jepsen's new song Call Me Maybe.
It really is the best thing we've seen on the interweb in a while.
It's basically all of them dancing around in hoodies and tracksuits at Carlos's. Which looks like the most fun house IN THE WORLD. And Beliebers, be warned, his amazing moves are sure to get you even more obsessed with him.
Now we're off to listen to this song another hundred times, and then plan a sleepover.
