Howard Stern's fans know her as "the lovely Beth O," the object of Double A's affections and the svelte blond model who's been by the shock jock's side since 2000. But on October 3, Stern and Beth Ostrosky made it official, [article id="1596361"]tying the knot[/article] after a [article id="1552390"]20-month engagement[/article].

They had a quiet ceremony officiated by Mark Consuelos, the husband of "Live With Regis & Kelly" co-host Kelly Ripa, and held at the ritzy Le Cirque restaurant in Manhattan. The wedding was attended by 180 guests, including Joan Rivers, Chevy Chase, Rob Zombie, Jimmy Kimmel, Sarah Silverman, John Stamos, Barbara Walters and Donald Trump. During the evening, the Sterns were serenaded by 1970s songbird Phoebe Snow, who sang the wedding classic "You Send Me," and Billy Joel entertained guests with a rendition of "The Stranger" during the reception. Train's Patrick Monahan also performed before the night was through.

"Chevy Chase doing an impromptu [and X-rated] speech was fun," Ostrosky told MTV News on Monday night outside the New York [article id="1596991"]premiere of "Filth and Wisdom,"[/article] a new film that marks Madonna's directorial debut. "Billy Joel serenading us was not planned, and my best friend got up and spoke. Jimmy Kimmel made a surprise speech at the altar as Mark Consuelos was officiating. It was so much fun."

The last few weeks have been especially busy for Mrs. Howard Stern, 36, who has been training for the upcoming New York City Marathon, set for November 2. Ostrosky, who is a vocal proponent of animal rights, is participating in the marathon to raise money for the North Shore Animal League. She hopes to raise more than $250,000 for her cause, which fans can support by visiting her Web site, GoBethO.org.

All the proceeds raised through Ostrosky's sponsorships will benefit the Animal League's mission to find permanent homes for more than 20,000 orphaned animals.

"Between getting married, the honeymoon and my marathon training, it's been crazy," she said. "I did my first 20-mile [run] on Saturday, and we moved. We've moved into a new apartment, so it's all at once."

How did Ostrosky keep up her training amid all the hectic wedding planning? "That, to me, is the top priority," she said of the marathon. "The getting-married part was easy. The planning was a little more difficult, but it was the training that took top priority."
