• Prince Pierre Casiraghi of Monaco — the 24-year-old grandson of the late Grace Kelly — was badly beaten Saturday at a trendy supermodel-filled Manhattan nightspot, the NY Post reported. Nightlife entrepreneur Adam Hock, 47, was charged with four counts of third-degree assault — but insisted to the paper that prince and his posse started the brawl. Casiraghi, whose face was bloodied, was treated at a hospital.

• Sooner or later, every political VIP writes a children’s book – and now it’s Mark Kelly’s turn. The astronaut husband of Gabrielle Giffords signed a deal with Simon & Schuster for “Mousetronaut: A Partially True Story.” The story of a mouse who goes into space — based on an idea he first had a decade ago, he told the AP, when his two daughters from a previous marriage were young — will be published in October.
