While the teaser made "All That Matters" seem like it an all-growns-up bump and grind, the full video presents something a bit more uncomfortable (or less uncomfortable, depending on your perspective). Which isn't to say that sex isn't in the air here — it is, big time — but Bieber moves all too easily from intensity to playfulness to tentativeness, like a master performer trying to see what role gets the best response.

The Killers have surely earned the right to stroll down memory lane and create homages to their most memorable videos, but they're also smart enough to make sure these facsimiles are different in one key way: It's Glee star Dianna Argon in the role of singer Brandon Flowers, nailing every look (and, yes, even the moustache).

2 Chainz might have culinary cred — see his Mealtime cookbook with the deluxe version of new album B.O.A.T.S. II: Me Time — but he's not cooking up food in this new "Fork" video.

While you might be tempted to view this as Rihanna showing the young'ns how Twerking is done — all respect to Ms. Miley, of course — keep in mind that photos from this shoot first crept out in May, way before the word was enshrined in the Oxford English Dictionary.

In fact there's a huge backstory here, teased in this little Twitter back and forth between director Vincent Haycock and Rihanna:

@vincehaycock luckily none of that matters, just take your name off the check while u at it! Whatever your issue is leave my fans out of it

How's the video itself? Well, it's got pasties, strippers, twerking and a whole lot of content that's probably the unsafe side of NSFW. To summarize the wise man Chazz Michael Michaels, "It's provocative."
