E! has announced Holly's World, a new The Girls Next Door spinoff following former Hugh Hefner girlfriend Holly Madison and her new life in Las Vegas, will premiere on Sunday, June 13 at 10:30PM ET/PT.

Holly's World will document various aspects of Madison's life -- including her starring role in Vegas' Peepshow stage show, traveling to Mexico for a calendar shoot, getting involved in local politics, and maintaining a busy social life.

"Audiences fell in love with Holly on E! and fans are eager to follow her next chapter," said network programming executive Lisa Berger. "The series will feature Holly and her family of friends as they take on new loves, careers and ambitions together." 

Madison appeared in the first five seasons of E!'s The Girls Next Door -- along with Bridget Marquardt and Kendra Wilkinson -- as one of Hefner's girlfriends.

While Madison and Hefner discussed marriage and she openly stated on several occasions that she wanted to have children with him, he eventually revealed that there would be no wedding and the two split in late 2008.

Madison, Marquardt and Wilson all subsequently moved out of the Playboy mansion prior to The Girls Next Door's sixth-season premiere last October.

E! ordered the eight-episode series in January and it is being produced by Prometheus Entertainment, Alta Loma Entertainment and Fox Television Studios with Kevin Burns -- who also produces The Girls Next Door as well as Wilkinson's Kendra spinoff -- serving as executive producer.
