Justin Bieber is back supporting Carly Rae Jepsen and this time, there's even more star power!

The Biebs, 21, along with his besties/clique/squad (whatever you prefer), Ariana Grande, 21, Kendall Jenner, 19, and lots of other pretty people have made a lip-sync video for the 29-year-old singer-songwriter's new single, "I Really Like You.” Apparently, getting Tom Hanks to star in her music video was just the beginning!

The video also features 35-year-old 'NSYNC alum Lane Bass, 24-year-old Korean rapper CL -- who is now also managed by Scooter Braun -- and Ariana's 32-year-old brother Frankie Grande.

It also features Justin's inability to keep his shirt on.

And showcases Ariana and CL basically being besties.

There's even some very cute moments between Kendall and Justin. Adorable, actually.

She goes up on his shoulders.

Not to mention this almost pregnancy announcement that would have BROUGHT THE INTERNET TO THE GROUND.

All-in-all the video seems to have done it's job, because now we can't get it out of our head.

Of course, let's not forget the original that started it all -- when Justin, Selena Gomez and Ashley Tisdale put "Call Me Maybe" on the map.

Damn it, now that will be stuck in our heads for another three years probably.
