Amber Rose and Wiz Khalifa had a wedding ceremony on Sunday in Philadelphia, a little more than a month after announcing they had wed at a courthouse in Los Angeles.

The 29-year-old former video vixen celebrated by twerking the night before the big day in front of her girlfriends. Twerking is a dance move that involves shaking the hips and bottom in a suggestive up-and-down motion. Rose, who wore a white jumpsuit, posted the video to Instagram with the caption "Only bad b---hes twerk the night before their wedding.”

Rose and her 25-year-old rapper husband had previously announced they would have a fall wedding. “Me and Amber got married today," Khalifa tweeted last month. "Weddings this fall. Thought I'd let yall know [sic].”

It had been speculated for months that they were already secretly married, and Rose frequently referred to Khalifa as “husband” in tweets and during impromptu interviews with the paparazzi.

Rose and Khalifa in October spoke about their relationship, and said they wanted to postpone their nuptials to include their first child, Sebastian, who was born on Feb. 21.

“There’s no date set yet," Khalifa told hip-hop magazine XXL last year. "But we’ll probably get licensed and married before the baby’s born, and do a wedding afterwards because it makes more sense for the baby to be in the wedding than for her to be pregnant.  Some people, they rush and do it. But, it works both ways.”
