BEVERLY HILLS

In its upcoming 12th and final season, "Two and a Half Men" will embrace a story line about gay adoption.

CBS chairman Nina Tassler told reporters at the TV critics press tour that the season will kick off with Walden (Ashton Kutcher) experiencing a major health scare that plunges him into an "existential crisis." In an effort to add more meaning to his life, he decides to adopt a child.

"He starts the process and he realizes it's very difficult to adopt a child as a single straight man," Tassler explained. The solution? Pose with Alan (Jon Cryer) as a gay couple in an effort to better his chances.

"Once and for all he decides, 'I'm going to propose to Alan and we're going to get married and adopt a child as a gay couple,'" she said.

Tassler called the story line a "great ride" and said she thinks it makes a "very positive statement" about the state of gay rights in the country.
