'Two And A Half Men' will be taking on their biggest storyline to date. Chuck Lorre, the creator of the popular sitcom, is planning to run a same-sex marriage storyline between Walden and Alan, who are played by Ashton Kutcher and Jon Cryer.

Kutcher's Walden will marry Cryer's Alan in order to adopt a child

The idea stems from Walden's ongoing struggles with his current life, but in order to get it more, he decides to adopt a child. However, he soon finds out it is "very difficult to adopt a child as a single, straight man."

On learning this, the entrepreneur billionaire will propose and marry Alan, who is also heterosexual, to help him become a father.

"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 at the Television Critics Association's summer press tour. "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?"

"There's going to be a wedding; we're a sitcom, we're going to have a wedding. Walden and Alan are going to get legally married. They have to get legally married to adopt," he added. "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."

Lorre fully understands that this sort of storyline will most likely be received with a backlash from many viewers, but he does hope the LGBT community don't get offended in anyway.

"I hope there's none," Lorre told E!News at the same event on Thursday (July 17th). "The show has always caused controversy. We have. There's no intention to insult or diminish anyone. The intention is to create laughter. That's it. Great laughter and if it's got a heartbeat in there that would be nice, too."

So why CBS decide to air a gay marriage plot for the sitcom's final season?

"This is our last year. So we wanted to center the last year on Alan and Walden and have those guys do an adventure together the whole season because they're so great together," head writer Jim Patterson added.
