Beth Ostrosky (born July 15, 1972 in Pittsburgh) is an American model, actress and television host who is the girlfriend of radio personality Howard Stern.
Born in Pittsburgh, Pennsylvania, Ostrosky began her modeling career by doing fashion shows at the age of 9. Continuing to model through her high school days at suburban Fox Chapel, Pennsylvania, Ostrosky moved from Pittsburgh to New York soon after graduation to pursue her modeling career.
Soon after her New York arrival, talent scouts began to take notice of Ostrosky, and began to offer her bit parts in movies and television campaigns. Ostrosky received her first major role playing opposite Ben Stiller as one of the daughters of Stiller's "supposed" birth parents in the 1996 film Flirting with Disaster.
Ostrosky played a more prominent role opposite Amanda Peet in the film Whipped four years later. Meanwhile she continued to pursue her modeling career, becoming known for her specialization in swimsuit spreads.
In 2000, "Beth O" met radio personality Howard Stern at a dinner party. They soon after were considered a couple, though it would take Stern nine months before confirming this on his morning radio show. They are still together, and she has been known to call into the show from time to time.
Ostrosky continues to model. She also does some television, most recently seen in the new season of G4 show Filter, and the Spike TV series Casino Cinema. She has also appeared in her own line of calendars as well as on the covers of several magazines. Ostrosky has been named in the Top 100 Sexiest Women of the Year in 2002, 2003, and 2004 by the readers of FHM.
Ostrosky frequently appears in various forms of media with the English Bulldog that she and Stern acquired in 2002, whom they named "Bianca Romijn-Stamos".
