Maybe to make sure he’s not the most hated person on The Tonight Show when it returns next week, Jay Leno has booked a guest more controversial than himself. Sarah Palin will join Leno on Tuesday for his second show as host of The Tonight Show. His first show will feature Olympians including Shaun White and Lindsey Vonn. Other episodes in Leno’s first two weeks will feature Simon Cowell and the Jersey Shore cast. Interesting aside: Adam Lambert’s Web site says he’ll appear on March 2, the same day as Palin; but Leno’s schedule makes no mention of Lambert.
