Jay Leno sets 'Tonight Show' guests

First two weeks to include Sarah Palin, Simon Cowell

Jay Leno's first two weeks back as host of NBC's "Tonight Show" features a celebrity-packed lineup as NBC tries to revive the late-night franchise.

Leno will welcome former Alaska governor Sarah Palin, the cast of MTV's "Jersey Shore," "American Idol" judge Simon Cowell and Olympians Apolo Anton Ohno, Shaun White and Lindsey Vonn.

NBC relaunches the "Tonight Show" with Leno back at the helm on Monday. Leno's ratings and reputation took a beating while hosting "The Jay Leno Show" at 10 p.m., and "Tonight Show" viewership likewise declined under Conan O'Brien (until his final week). Having a big-name draws like Palin can only help as NBC tries to make "Tonight" appointment viewing once again.

Leno's other guests his first couple weeks include Dakota Fanning, Kim Kardashian, Jamie Foxx and Morgan Freeman.
