If you were a night owl in the 1990s, you probably remember watching USA: Up All Night with Rhonda Shear. Shear discusses her new book, Up All Night: From Hollywood Bombshell to Lingerie Mogul, Life Lessons from An Accidental Feminist, in which she writes about her family and career as a TV personality. Born in New Orleans, Shear was a former Miss Louisiana who posed for Playboy and even ran for office in her hometown. She ditched law school for L.A. in the ‘70s, where she worked as a stand-up comic and acted in film and TV roles, including The Dukes of Hazzard, Happy Days, Three’s Company, Married with Children and Spaceballs. But Shear is best remembered for USA: Up All Night, which ran from 1991-1998. With her high-pitched voice and ditsy persona, Shear hosted the late-night weekend show on the USA network, which mixed interviews and corny skits with horror and B-rated movies with titles like Assault of the Party Nerds and Cheerleaders’ Wild Weekend (you may remember Gilbert Gottfried hosted the show’s N.Y. version). Shear is now owner of an intimate apparel company. Barnes and Noble The Grove; Feb. 11, 2 p.m.; free.
