Getting your Trinity Audio player ready...

If they all got onstage together, fiftysomething supermodel Lauren Hutton, retired Chicago Bears linebacker Mike Singletary, photographer Annie Leibovitz and former U.S. Sen. Paul Simon would sure make a strange supergroup. But, in fact, they’ll be appearing separately this week. Hutton speaks about personal style at 6:30 p.m. Tuesday as part of the ongoing “Cartier: 1900-1939” exhibit at the Field Museum, Roosevelt Road and Lake Shore Drive. Tickets: $15, $10 for members and $12 for students; 312-665-7400. Singletary guests on the Score’s “Chicago Bears: 80 Years of Gridiron Legends” program at 9 a.m. Sunday, also at the Field Museum; call 312-922-9410. Simon speaks on “Tapped Out: Is a Water War in Our Future?” at 7:30 p.m. Wednesday at the College of DuPage’s Arts Center Mainstage, Park Boulevard and 22nd Street, Glen Ellyn. Tickets: $9, or $8 for students; 630-942-4000. And Leibowitz signs her new book, “Women,” at 7:30 p.m. Tuesday at the Swedish American Museum Center, 5211 N. Clark St. Free. 773-769-9299.
