"Gossip Girl" (8 p.m., WGN-Channel 9): I'm not saying that they're desperate for ratings. But tonight's episode includes Leighton Meester's new single with Robin Thicke, and a ménage-a-trois with three major characters.

"Lincoln Heights" (8 p.m., ABC Family): In the fourth-season finale, Lizzie tries to save her school musical. Now that's a cause I can support.

"CSI: Miami" (9 p.m., WBBM-Channel 2): Be warned, this is a commitment. Laurence Fishburne of the Las Vegas crime lab follows a severed leg to Florida. The storyline continues on "CSI: NY," and finishes up on "CSI: Crime Scene Investigation."

"Lopez Tonight" (10 p.m., TBS - and tonight only, also on truTV and TNT): The first episode of George Lopez's talk show includes Ellen Degeneres, Eva Longoria-Parker and Kobe Bryant. Also coming up: Jessica Alba, Charlie Sheen, Sandra Bullock and Jamie Foxx.
