Isis, America's Next Top Model Isis, America's Next Top Model

The first transgendered contestant on America's Next Top Model will undergo surgery soon to become physically female, with the help of the show's host, Tyra Banks.

In an episode of The Tyra Banks Show that aired Tuesday, Banks surprised 22-year-old Isis King with Dr. Marci Bowers, who offered to evaluate Isis and perform the surgery.

"This is not happening," Isis said, adding that she felt "like I'm about to wake up."

Bowers, who has undergone the procedure herself and is the star of a new reality series, Sex Change Hospital on We tv, told the surgery will take place early next year.

The season finale of Top Model airs Wednesday. Isis, who was born Darrell Walls and has described herself as "a woman born physically male," was the fifth contestant to be sent home from the show.

She told Banks on Tuesday's show that she felt uncomfortable taking photos in a pool because she had not yet undergone surgery. She was sent home after the photos. She was living in a Maryland homeless shelter before she appeared on Top Model.
