So, before Amber Rose ties the knot again with her boo Wiz Khalifa, the blonde bombshell decided to celebrate with a round of booty twerking. Miley Cyrus, please take notes.

On Saturday night (Aug. 17), during Rose's bachelorette party, the statuesque mom shared on her Instagram a video of her popping that booty to Luke's classic jam, 'I Wanna Rock (Doo Doo Brown),' playing in the background.

"Only bad bitches twerk the night before their wedding," she wrote.

If you ever questioned why Wizzy is wife-ing her up, these two glorious Instagram videos should answer your inquiries.

Rose's booty cheeks look very flexible, and, in the words of Beyonce -- bootylicious! Keep in mind, the 29-year-old model just gave birth to her baby boy, Sebastian Thomaz, six months ago. Clearly, Rose has been hitting the gym and doing butt exercises.

We also have to give a special thanks to Instagram for implementing its 15-second video app on its service. It's quite a useful tool.

Judging by the videos, it looks as if Wiz and Rose will get married later today (Aug. 18) in Pittsburgh, Pa.

We'll keep you posted if the bride and groom decides to twerk it on the dance floor at their reception.

Congratulations to Wiz Khalifa and Amber Rose on their pending nuptials!
