The four years Brooke Shields spent hitting the books at Princeton University gave her the skills to survive the tribulations of show business, the actress told students at her alma mater Monday. Urging them to live life to the fullest and take nothing for granted, Shields teared up as she delivered the keynote speech at Princeton’s annual Class Day ceremony to honor graduating seniors. “My education enabled me to survive this industry — one that predicates itself on eating its young,” she said. Shields, who was a prominent Calvin Klein model when she enrolled at Princeton, reminisced about her college experiences, such as having her entire academic record printed in Life magazine. “Or when George Michael tells you he doesn’t want to date you because he wants to focus on his solo career — then you find out he’s gay,” she said, rolling her eyes. Shields played the title character in the late 1990s television series “Suddenly Susan” and also starred in TV’s “Lipstick Jungle” and the film “The Blue Lagoon.” She graduated from Princeton with honors in 1987, with a degree in Romance languages and literatures. The annual ceremony is planned and presented by graduating students, and usually includes a heavy dose of humor. Previous years have featured former President Bill Clinton, comedian Stephen Colbert and news anchor Katie Couric. … Hip-hop singer Sean Kingston crashed his watercraft into a Miami Beach bridge Sunday evening, and on Monday was in the intensive care unit at a hospital, his publicist said Monday.
