Watch Amber Rose Give Wiz Khalifa The Best No.1 Album Dance Ever

Now 'this' is twerking.

Sorry, Nielsen SoundScan, you’ve just been one-upped!

Before today, the album sales tracking system was solely responsible for delivering Wiz Khalifa’s best week ever by tallying up the numbers to land the Pittsburg rapper’s Blacc Hollywood LP the #1 spot on the Billboard albums charts.

But that was before the "We Dem Boyz" MC’s wife Amber Rose came through with the grand twerk finale. That’s right, the blond bombshell posted the sexiest video ever on Instagram Friday (August 29) to celebrate her hubby’s first No. 1 album.

In the clip, the self-described “MILF” is wearing a blue camisole, making her glutes shimmy on beat to Wiz’s single, “A-- Drop."

“In honor of my Hubby's #1 Album #blacchollywood #A--Drop," she wrote in the caption.

We've been seeing a lot of Amber this week, as the video comes shortly after her Rose McGowan-channeling near-naked appearance on the VMA red carpet.

But of course, he had to post his own video of the celebratory twerking session.

Way to go Wiz! If these videos are going to become standard procedure, we definitely can't wait until you get another #1!
