'Two and a Half Men' to Feature Gay Wedding During Its Final Season

You may be surprised who is getting married and why.

— -- Two people will tie the knot during the 12th and final season of CBS' "Two and a Half Men," and you may be surprised who they are and why they're getting married.

CBS Entertainment President Nina Tassler confirmed to ABC News that Ashton Kutcher's character Walden will pop the question to Jon Cryer's Alan.

Tassler confirmed that Walden will have a health scare that causes him to make the commitment.

"Walden, in having kind of an existential crisis, he has a near-death experience and he is evaluating the meaning of life. He wants to adopt a child and it is particularly challenging to do so as a single male. So he decides that he and Alan should get married and they will adopt a child as a gay couple," Tassler said Thursday, while at the Television Critics Association summer press tour in Beverly Hills.

ABC News asked Tassler whether there has been any discussion regarding bringing back former star Charlie Sheen for the show's swan song. She simply answered, "Not at this time, no."

Sheen left "Two and a Half Men" in 2011 on acrimonious terms, having chastised creator Chuck Lorre and others involved with the sitcom. Sheen, who now stars in the FX comedy "Anger Management," has since attempted to make amends with Lorre.

The final season of "Two and a Half Men" premieres Oct. 30.
