Express Yourself, Gleeks

Tonight, one of the most anticipated hours of TV takes place as "Glee" (Fox, 9 p.m.) devotes its entire selection of musical numbers to Madonna.

Fans of the show already saw a glimpse of what tonight has to offer with the Sue Sylvester (Jane Lynch) shot-for-shot remake of Madonna's "Vogue" video, which was brilliantly executed.

I personally have never been a Madonna fan, but I think her music will lend itself well to "Glee." The episode centers on female empowerment as Will (Matthew Morrison) uses Madonna's music to try to get through to the Glee Club.

'MAD MEN' PREMIERE: "Mad Men" will premiere its fourth season July 25 on AMC. The network will then debut its new political thriller, "Rubicon," the following week.

TUESDAY'S BEST BETS: I'm a bit surprised that "American Idol" (Fox, 8 p.m.) didn't try to land Madonna herself as a tie-in to "Glee." Instead, Alicia Keys is the guest singer.

As far as I can tell, there are no musical numbers set for "Lost" (ABC, 9 p.m.) tonight, just its regular awesomeness as Fake Locke and Hurley have a sit-down. It's followed by a new "V" at 10 p.m.

NBC airs two hours of "The Biggest Loser," also without musical numbers, followed by a new "Parenthood" at 10 p.m.

CBS and CW are reruns tonight.

On cable, FX has a new hour of "Justified" at 10 p.m.
