Christina Aguilera, Sarah McLachlan Highlight A Lady-Centric 'Late Night Lineup'

Did everybody enjoy that little vacation? After a quiet week that saw several shows extend their Memorial Day weekends into extra-strength vacations, the entire late night slate is back with a vengeance this week (save for "Last Call with Carson Daly," which won't be back for at least another month). The push to promote big-time blockbuster movies (you'll be seeing a lot of cast members from "The A-Team" this week) as well as high-profile summer tours (Sarah McLachlan's Lilith Fair re-launch) and album releases (Christina Aguilera's Bionic is back on, which means the after-hours shift is going to be heating up.

The guests on David Letterman's couch this week include "American Idol" winner Lee DeWyze (Monday, June 7), Lilith Fair mastermind and headliner Sarah McLachlan (Tuesday, June 8), "A-Team" star Bradley Cooper and pop diva Christina Aguilera (Wednesday, June 9) and "The Karate Kid" star (and Justin Bieber collaborator) Jaden Smith (Thursday, June 10).

"The Tonight Show" has a quieter list of Hollywood types on the couch (highlighted by Chris Rock and Snooki, both of whom will sit for chats on Tuesday), but Jay Leno has five nights of killer music: Hole (Monday), Sting (Tuesday), OK Go (Wednesday), Alanis Morissette (Thursday) and Against Me! (Friday, June 11). That's something for everybody, isn't it?

Jimmy Kimmel only has two shows this week, though he will have a performance by Taio Cruz on Thursday. Meanwhile, Jimmy Fallon will deliver Kings of Convenience (Monday), Phish (Wednesday) and Sarah McLachlan (Thursday) as well as chats with Jessica Biel and Bradley Cooper (again!). Tune in to "Lopez Tonight" on Monday for a performance from Hanson, and stay up late Thursday to see Lil Jon and LMFAO start the party.

As far as daytime is concerned, there's not very much music in the daylight hours this week. "The Ellen DeGeneres Show" is on vacation (after doing both her talk show and "American Idol" for the better part of six months, she deserves the time off) and "The View" offers little more than a performance by Usher on Thursday. Otherwise, it's mostly quiet while you're awake, which is why you should conserve your energy for all the after-hours action this week.
