THE controversial, first trans gender contestant on “America’s Next Top Model” yesterday had her coming out party on “The Tyra Banks Show” to talk about her new life, after a sex-change operation, as a woman.

It is the first TV appearance for Isis King — who appeared last fall on the modeling-competition show as a pre-op trans-female — since the surgery.

The operation to go from a male to an anatomical female took four hours and 15 minutes to complete, Tyra said.

“Automatically I felt more comfortable,” Isis says. “I was ready to walk around the house in my little shorts.”

The 22-year-old, who was born Darrell Walls, made it through three “ANTM” challenges last year before being eliminated because she was uncomfortable wearing a swimsuit during a shoot in a pool.

Banks also invited Isis’ surgeon Dr. Marci Bowers — who appeared in 2004’s “CSI” episode “Ch-Ch-Changes,” involving the murder of a transgender woman — onto the show to explain the procedure. Tyra got Dr. Bowers to donate the operation, which typically costs between $20,000 and $35,000.

To show off Isis’ new body, Tyra had a trio of new photos of her in a bikini, similar to the shoot that got her booted from “ANTM.”

A moment later, her boyfriend, who appeared on the show with her, whipped out a diamond ring and proposed.

She accepted with a shocked, “Yes. Oh my goodness. Are you serious?”
