"NCIS," television's most popular drama, offers its season finale at 8 tonight on CBS. The previews suggest that a catastropheÂ hits the headquarters.Â The hour episode will feature guest stars Jamie Lee Curtis, Richard Schiff (as a very nasty villain) and Scott Wolf.
Other highlights tonight:
Do you have any doubt about which celebrity is leaving "Dancing With the Stars"? Singer Katherine Jenkins suffered a back injury during her second dance Monday, and that sad development probably means she's going. The results show starts at 9 on ABC. Carrie Underwood, Alanis Morissette and Mary J. Blige are set to perform.
Fox counters with two hours of "Glee" at 8 andÂ a guest appearance by Lindsay Lohan. Maybe that's a sign of how this once charming series has lost its mojo.Â Does Lohan matter more to viewers than the nationals? The "Glee"Â series finale will airÂ next Tuesday.
CBS expands the series finale of "NCIS: Los Angeles" to two hours, starting at 9. The move should mean good things for CBS' ratings. The competition at 10 includes the season finales of ABC's "Private Practice" and NBC's "Fashion Star."
