Jay-Z and Pregnant Beyonce Knowles Pictures at US Open

Jay-Z and Beyoncé Knowles were in the stands yesterday to check out the action at the US Open in Queens. They were in the stadium to watch the men's final match and see Novak Djokovic defeat reigning champ Rafael Nadal. The expecting couple are home in the Big Apple following a vacation in honor of her 30th birthday that took them, by yacht, from Italy to Croatia, where Beyoncé wore a bikini for a day of exploring. Jay-Z is due to wrap up his time at home soon, though, when he and Kanye West head to Birmingham, AL, to rehearse for their Watch the Throne tour, which kicks off Sept 22. in Detroit.
