He's going to be ALL woman soon!

Bruce Jenner has scheduled his final gender reassignment surgery, Radar reports. The procedure is set to follow his tell-all interview with Diane Sawyer, which airs April 24.

"Bruce is now ready. This is a very, very big step for Bruce to take, and the time is approaching quickly. The surgery will take place at the end of May/beginning of June. It’s a very intensive surgery," a source told the website.

According to Miami-based plastic surgeon Dr. Mel Ortega, who does not treat Jenner, the operation can take anywhere from six to eight hours and is extremely intricate. "The testicles are history but the rest is preserved to create the neo-vagina. The tissue is never removed from the body, with the exception of incorporating skin grafts if there’s isn’t enough material," Dr. Ortega explained.

We're happy for him that he will finally be comfortable in his own skin!
