Miley Cyrus and Nicki Minaj have serious competition. The now newly-wed Mrs Khalifa aka Amber Rose has posted a video of herself twerking in nothing less than her white wedding gown!

Was it the pre-marriage jitters that led to the new mother show the world some really serious twerking moves or she wanted to prove a point that she had no marriage jitters at all? Whatever the reason, the actress delighted (maybe!) her fans by posting her twerk video on August 18.

"Only bad b-tches twerk the night before their wedding," was the caption she added to a clip of her shaking her rear.

One look at the video and you see Rose with her big fat derriere twerking without music in her wedding dress. The bride-to-be looks super confident on her wedding day and seems to be warming up for the big day ahead of her. The video already has around fourty five thousand likes and several comments where people can be seen comparing her meaty-rear with Miley's slim butt.

The video appears to be shot by one of her friends who are encouraging her to twerk more. The bald bride has decided to tie the knot in Pittsburgh, with the father of her baby Wiz Khalifa.

Wiz Khalifa and Amber Rose are already legally married but the couple wanted to celebrate the wedding ceremony later. Last week, Amber posted the picture of her elaborate wedding dress being packed in a carton box by more than two-three people.

"Aw @sammyrexic & @priscillaono packing my wedding dress #pixburghbound," the would-be-bride said in a picture. Going by the picture, it looks like the couple has plans for an elaborate wedding party.

Another picture shows the wedding dress arriving in a truck and Amber wrote a caption "My wedding dress... Yea, it's that serious!"

Rose began dating rapper Wiz Khalifa in early 2011 and the couple got legally married in July 2013, but did not plan any wedding ceremony then. Amber also has a son with Khalifa named Sebastian Taylor Thomaz, who was born on Feb 21 this year. Amber was also in relationship with Kim Kardashian's beau rapper Kanye West for almost two years.
