In the next episode of "Mom," Bonnie (Allison Janney) and her fiance Adam (William Fichtner) are not on the same page about their upcoming wedding.

The trailer and promotional photos for the upcoming installment, which is titled "Sex Fog and a Mild-to-Moderate Panic Attack," were just released recently, and they show the formally-dressed Bonnie and Adam talking in the living room of her apartment.

They had just arrived from a friend's wedding and are now discussing their own, which will happen in a few months. The both of them look displeased as Bonnie turns away from Adam and he sulks in his wheelchair. Apparently, they are not on the same page about how they want their wedding to be. Bonnie decides to vent out her frustrations at her daughter Christy (Anna Faris).

She meets up with her later at the coffee table and starts talking about her experience at her friend's wedding with Adam. "All of a sudden he wants a traditional church wedding," Bonnie says with frustration.

She thought that they had already decided that they were going to have a quiet wedding with just a few friends and family. Now, she has to contend with Adam about not having it in a church, which she does not like.

Christy slides in jokingly, "Doesn't he know that if you walk into a church wearing white, you will burst into flames?"

In the last episode, Christy had a hard time keeping up with her long-distance relationship with her boyfriend. She, unfortunately, succumbed to spending a number of nights with Cooper (Michael Arangano), a fling from a few months ago. She ended up coming clean with Bonnie and Adam, his boyfriend's brother, who just brushed it aside and laughed.

"Mom" season 5 episode 11 will hit the airwaves on Thursday, Jan. 18, at 9 p.m. EST on CBS.
