CHUCK LORRE has a plan to bring CBS’ veteran comedy “Two and a Half Men” full circle, but it certainly isn’t without controversy.

    The comedy’s 12th and final season will see Ashton Kutcher’s Walden propose — and marry, according to exec producer Lorre — Jon Cryer’s Alan after an existential crisis that propels him to do more with his life and adopt a child.

    After the character realizes that it’s “very difficult to adopt a child as a single, straight man,” to hear CBS Entertainment chairman Nina Tassler tell it, Walden — who is straight — will marry the heterosexual Alan in order to achieve his goals.

    “You’re going to see two men who are not gay but are going to raise a child with a great deal of love and attention,” Lorre told The Hollywood Reporter last week. “Their sexuality is irrelevant to loving and caring for a child, which maybe that’s the big story that we wind up telling: taking a kid out of the system and giving him a home. What’s better than that?”

    Lorre says the adoption story will help bring the show full circle, though he is aware that there’s the opportunity to upset the lesbian, gay, bisexual and transgender community, with gay marriage not legal in every state and gay adoption still an uphill battle.

    “People in the other parts of the country will see a show where two men are trying their very best to care and raise a child. How we get there might involve some subterfuge but the storyline is about two men trying to do the right thing.”(SD-Agencies)
