Walden (Ashton Kutcher) and Alan (Jon Cryer) are going to tie the knot on the season 12 premiere on Thursday, Oct. 30 on CBS.

"We've had a wedding almost every season, yet I've managed to remain single," Cryer told Entertainment Tonight. "This might be the one that sticks."

During the premiere, veteran singer Michael Bolton will even serenade the two at the altar. The 61-year-old changes the lyrics to Percy Sledge's legendary 1966 hit, "When a Man Loves a Woman," to "When a Man Loves another Man." To no surprise, Alan will also shed a tear during the ceremony held in California where gay marriage is legal.

But, the nuptials aren't going to happen because the two suddenly realize they are in love. Instead, Walden wants to adopt a child and discovers that being married Alan is his only chance since it's very hard for an individual to do so.

"Walden is going to have a major health scare and it is going to give him a bit of an existential crisis," CBS Entertainment chairman Nina Tassler said during the Television Critics Association press tour over the summer.

"I think it's a very positive statement," she said in reference to the controversial episode. "[Walden believes he is] going to adopt a child as a gay couple, and the reality is he can do that. In a universe where at one point you couldn't do that, and now you can, I think that's a much more positive statement that he's making."
