Hugh Hefner

The Playboy Mansion is officially for sale.

Things got crazy at the Playboy Mansion the other night, and Playmate Anna Sophia Berglund — Hugh Hefner’s new “number one” girlfriend — got the octogenarian to engage in a bit of planking.

Apparently, Hugh Hefner has already moved on from “runaway bride” Crystal Harris. According to TMZ, 25-year-old Anna Sophia Berglund (pictured, left) has taken up residence in the 85-year-old’s notorious bedroom. The pair has also been spotted kissing and calling each other “babe.”

Playboy icon Hugh Hefner has apparently found a solution to his magazine’s July issue, in which his ex-fiance, Crystal Harris, graces the cover with the now-awkward headline, “Introducing Mrs. Crystal Hefner.” Hefner explained his quick fix Wednesday on Twitter, saying, “Recent events call for a special sticker on the July cover. Look for it on newsstands.”

Well, so much for that: Hugh Hefner confirmed Tuesday that his wedding to 25-year-old model Crystal Harris has been called off. "Crystal has had a change of heart," he said via Twitter.

Last February, Hugh Hefner and his posse held a fundraising event at the notorious Playboy mansion. And though many decadent, debaucherous parties lead to a few exchanged diseases, this one resulted in over 100 people reporting pneumonia and flu-like symptoms after the evening's shindig came to a close.
