'Teen Mom' Star Tyler Shames Catelynn's Weight: 'I Don't Want No Heifer'

The honeymoon stage may be over for Catelynn Lowell and Tyler Baltierra, as he slammed her weight in a Teen Mom OG sneak peek.

Lowell, 24, revealed how she plans to join Weight Watchers again because it makes her "feel good." But despite her motivation to lose weight, Baltierra criticized her choice of lunch.

"That's a big a** quesadilla, it has a lot of chicken," Baltierra, 24, said. "It's your body, you could do what you want. Obviously I don't want no heifer for a wife!"

While Lowell laughed, TMOG producer Jessica seemed shocked by his comment.

"You come off so harsh sometimes," she said, as he responded, "I'm being honest! Would you want to be married to some big heifer?"

Lowell then asked her husband really thinks she's fat.

"No," he responded. "Just know that I love you no matter what."

She then revealed how she may choose to hold off on losing weight because they may be expanding their family soon.
