One Tree Hill @ 9pm
This show often attracts top music acts, especially for their episodes in which Peyton stages concerts. Tonight she organizes a USO show with headliners Angels and Airwaves and Kate Voegele (reprising her role as Mia). Haley is set to perform as well, except she's hit with a case of stage fright. Off stage, Lucas tries to come to terms with Peyton and Julian's romantic past, while Millicent confronts Mouth about his relationship with Gigi.
Gossip Girl @ 8pm
It's almost like it's the 1980s all over again when Cyndi Lauper and The Princess Bride star Wallace Shawn appear in tonight's episode! Lauper appears as herself (it turns out Blair is a fan), and Shawn appears as Eleanor's new beau, Cyrus Rose. (Blair's not a fan of his, so she tries to break them up.) Elsewhere, Jenny moves in with Agnes, and Dan starts hanging around the Bass family in order to get dirt on Bart and write an exposé on him. Way to get on Chuck's bad side yet again, Dan.
Chuck @ 8pm
Chuck confronts the "ex factor" tonight. Jordana Brewster begins a multi-episode guest-star stint as Jill, Chuck's former flame and college sweetie, a beauty who broke his heart and derailed his life. Chuck runs into her by chance and, of course, embellishes his status in life to impress her. But Chuck quickly springs into spy mode upon discovering that her research-scientist boss may be involved in the development of a bioweapon. Meanwhile, Buy More's efficiency expert (Tony Hale) enforces a mandatory CPR course, conducted by none other than Captain Awesome himself.
Heroes @ 9pm
Arthur Petrelli has certainly been busy over the past few weeks: building an army, wreaking havoc with his sons, ordering murders, etc. But what led him to his current mission? Tonight we find out as Hiro takes a look into the past and discovers what drove the Petrelli patriarch down the dark path leading to Pinehurst.
