Howard Stern's Fiancée: 'We're Not Married!'

Despite a slew of wedding reports, it seems Howard Stern and Beth Ostrosky are still single.
"We are not married," Ostrosky told PEOPLE Thursday night at The Bridge, a golf club in Bridgehampton, New York, where Sotheby's unveiled works by artist Damien Hirst for an upcoming auction.
So what sparked all the wedding talk last week? She said the happy couple hosted a "family celebration" at their Hamptons home on Aug. 23 – prompting the press to assume it was the big day.
"It was a beautiful, beautiful event," said the model, who has been engaged to the shock jock since last Valentine's Day. "I wore a white dress and Howard wore white pants and a blue shirt. But it was just a celebration of the wedding. The real thing is in October."
Instead of presents, guests made donations to Ostrosky's charity run, GoBethO.org. (By running the New York Marathon, she hopes to raise $262,000 for the North Shore Animal League America.)
The two have said for months that they're planning a fall wedding, either in New York City or the Hamptons.
Thanks to the pre-wedding bash, Ostrosky said, "Our families were the first ones [to toast] ... our upcoming nuptials."
