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 the day before commencement.

The model and actress jokingly reminded the a cappella singing group that rejected her decades ago that she'll be starring in her fifth Broadway musical this year. She questioned how far down she was on the list of preferred headliners for the ceremony.

"Who couldn't they get? Why did Snooki pass?" she mused, referring to Nicole "Snooki" Polizzi, star of the reality TV show Jersey Shore, who spoke at Rutgers University in March.

Singer hurt in crash

Hip-hop singer Sean Kingston was in the intensive care unit of a Miami hospital Monday after crashing his watercraft into a Miami Beach bridge, publicist Joseph Carozza said.

Kingston and a female passenger were injured when the watercraft hit the Palm Island Bridge around 6 p.m. Sunday, said Jorge Pino, a spokesman for the Florida Fish and Wildlife Conservation Commission. A passing boater saw the accident and took the two on board his vessel, the Miami Herald reported.

Authorities are investigating the crash, and "nothing at this point would indicate that alcohol played a role," Pino said.

Kingston rose to fame with his 2007 hit "Beautiful Girls," and his self-titled debut album sold more than a million copies worldwide. He recently toured with Justin Bieber.
