Janelle Monae And 'Sex And The City 2' Rule The 'Late Night Lineup'

Memorial Day is this weekend, which means the unofficial start of summer is finally here. It's time for barbecues, road trips, poolside naps, baseball games and paying slightly less attention at work than normal. It also means that the late night shows will be disappearing more frequently, ducking into reruns so the various writing, production and performance staffs can enjoy their summer vacations without having to worry about making up gags about Robert Pattinson and the coming midterm elections. Take David Letterman's show, which will only have three new episodes this week so everybody can stretch Memorial Day into an extra-long weekend. Still, he'll welcome "American Idol" reject Casey James on Monday (May 24) and Sarah Jessica Parker and the Black Keys (not together, sadly) on Tuesday (May 25). (It should be duly noted that the women from "Sex and the City 2" are literally going to be everywhere this week, so you'll know all of Kim Cattrall's talk show jokes by the time that movie drops on Friday.) Wednesday's (May 26) show is especially odd, as it features Don Rickles, Piedmont Bird Callers and a musical performance by John Prine (featuring My Morning Jacket frontman Jim James).

"The Tonight Show" is delivering a full week of shows, featuring Russell Brand (Monday), "The Celebrity Apprentice" winner Bret Michaels (Tuesday) and a performance by Hanson (Wednesday). Interestingly, band leader Kevin Eubanks is scheduled as a guest on the show on Friday (May 28). Could Leno be revealing his new music chief, or will we find out what's next for Eubanks?

Following his big "Lost" event on Sunday night (May 23), Jimmy Kimmel is back with a handful of shows this week highlighted by two appearances from Stone Temple Pilots on Wednesday and Thursday (May 27). Over on "Late Night With Jimmy Fallon," you can catch the Black Keys on Wednesday and Reflection Eternal (the team of Talib Kweli and DJ Hi-Tek) on Thursday.

Jon Stewart and Stephen Colbert are both already on vacation this week, though George Lopez will have performances from Paper Tongues (Monday) and Janelle Monae (Thursday) on "Lopez Tonight." But the real action this week (strangely) is on "Live with Regis and Kelly." The syndicated daytime show will have interviews with Bret Michaels on Monday, the Jonas Brothers on Tuesday and more cast members from "Sex and the City 2" than you can shake a stick at. This week, Regis is on the pulse.
