America's Next Top Model
8 pm/ET CW
Top Model is back, baby! And tonight's playful two-hour 12th-season premiere brings together 34 gorgeous goddesses to Caesar's Palace in Las Vegas. Of course, only 13 will survive the initial hour and move into a luxurious Upper East Side apartment in New York City where the real fun and catty games begin. The beautiful baker's dozen walk their first runway and then bring classic childhood games to life in a joyous Central Park photo shoot. — Tim Holland

What an island! Locke even rose from the dead to return. More likely, he was resurrected (if that's what happened) because his body was returned. With transformative powers like that, you'd think that Ben and Widmore are fighting over it because they each want to open a spa there. No? You're right. Smoke monsters aren't tourist-friendly. And all the shooting! The powers don't work on everyone. There's more shoot-em-up tonight, and you'll also meet new folks. But the main focus is on Juliet and Sawyer. — Paul Droesch

High School Reunion
The hijinks perpetrated last week by merry pranksters Dennis and Manny may have been all in good fun, but it was no laughing matter to some of their classmates, who go as far as to demand that the lead reunion-crasher, Dennis, be shown the door. Meanwhile, Tom is out of sorts and looking for an explanation when Scott H. asks Kara — Tom's ex-wife — out on a hall pass. — Joe Friedrich

Make Me a Supermodel
10 pm/ET BRAVO
Bravo's got a passion for fashion: It's a new season of catwalks and catfights as Season 2 of the model-themed competition show kicks off tonight. Sixteen new model-wannabes invade New York City to learn about pose and poise, and they'll scale new heights in their very first challenge. Here, they must conjure up an intimate moment — in a glass box suspended high above New York. And the new season brings a new look. While Tyson Beckford returns as host, Season 1 cohost Niki Taylor does not. In addition, Nicole Trunfio is the models' mentor, and the judge panelists include designer Catherine Malandrino, model Jenny Shimizu, photographer Perou, and model scout Marlon. — Dean Maurer

Hudson Plane Crash — What Really Happened
With a war on two fronts, rampant layoffs, foreclosures and bailout controversies headlining the news, it's safe to say this country has been aching for a story we can all feel good about. Enter US Airways pilot Chesley Sullenberger, the hero of Flight 1549, who, on Jan. 15, 2009, pulled off an emergency landing in the Hudson River without a single life lost. Film footage and interviews with crew members and other survivors highlight this look back at the miraculous landing. — Michael Chant
