'Teen Mom' Catelynn Lowell Fight with Tyler Baltierra: Will MTV Couple Call Off Wedding? [WATCH]

Teen Mom star Catelynn Lowell's relationship with Tyler Baltierra may not be as perfect as it seems, especially after the last episode of the MTV hit series where the reality dad made his fiancé feel badly about her pregnancy weight gain. Could this lead to the adorable pair calling off their upcoming wedding?

In a "Teen Mom OG: Featured Moment" on MTV.com, little Novalee's mom opened up about her struggles with weight and how it has affected the reality couple's bond.

"At first I used to get really defensive of it, but he's like, 'Well, I just want you to feel good about yourself when you're walking down the aisle,'" Catelynn said. "Tyler's super supportive about my weight loss. He encourages me a lot to go to the gym and do things that he knows I want to do. He's really good at helping me make better decisions, as in when we go grocery shopping ... he's really supportive of me. He'll do anything to help me succeed in what I want to do."

The Michigan native went on to give an example of something she doesn't appreciate he does, "The only thing I really told Tyler was I just don't like it when we're at a restaurant and he's like, 'This salad looks good,' and I told him, 'That makes me not want to eat the damn salad. Now I'm just gonna eat a freakin' cheeseburger because you told me to eat a salad.'"

This isn't the first time Catelynn and Tyler fought on television that led to the MTV mom breaking down. The cute pair appeared on VH1's Couples Therapy where Tyler called off their wedding because he wasn't ready to get married, but later changed his mind.

As MStars News reported, the Conquering Chaos authors blasted haters on Twitter for criticizing them for having a baby after placing their first child up for adoption.

"So sick of the ignorance in the world," Tyler posted. "Just because you place a child for adoption doesn't mean your [sic] not allowed to have another #GetReal."

Do you think Catelynn should be upset at Tyler for the comments about her weight or does he only have good intentions?
