Tyra Banks surprises America’s Next Top Model contestant Isis King on her show Tuesday with a free sex change operation.

Isis King is the first transgender contestant to have appeared on America’s Next Top Model.

US Weekly quotes King as saying “This is not happening! [I feel] like I’m about to wake up.”

King hasn’t gone in for the chop yet because she couldn’t afford the $20,000 to $35,000 price tag. Dr. Marci Bowers, “a top sex change surgeon who has gone through a sex change herself” agreed to do Isis’ chop and reconstruct for free.
