Proving the catwalk is treacherous, an "America's Next Top Model" contestant fell not once, but twice -- the second time getting smacked off the runway by a giant, swinging pendulum!

Descending a magnificent staircase in a golden one-shoulder Rachel Roy gown, Tennessee model Alexandra -- one of cycle 14's plus-size competitors -- crashed and slid to her knees. Her dress and knee badly gashed, she proceeded to the runway with a steely "I mean business" gaze, only to be catapulted off the catwalk by a large pendulum (a prop for the show).

Alexandra pulled herself back onto the stage, tore the train off her dress in a dramatic flourish that seemed scripted (it wasn't!), and strutted off, displaying tears only when she arrived backstage.

Despite her unsteadiness, the 21-year-old's grace under pressure impressed the show's runway coach, Miss J. Alexander, and Roy, who was in the front row to witness the drama.

After giving the young model a dressing down for looking angry after her first fall, the experts later gave her props for keeping it together. Um, we think she deserved a standing ovation for her glamazon-like efforts.

Alexandra, to her credit, seemed most upset that her "beautiful dress" was ruined. Her can-do attitude later held her in good esteem with the judges, including this season's new edition, Vogue Editor-at-Large André Leon Talley.

Alexandra wasn't even on the chopping block when it came time for the "ANTM" judges, which included Roy in a guest role, to consider who would be cut from the competition this week.

That distinction went to the deliberately bald model, Naduah, who Talley declared "dreckitude." Earlier in the night, the judges also eliminated Gabrielle, an 18-year-old from California.
