Teen Mom alum Tyler Baltierra says he's 'so beyond proud' of wife Catelynn Lowell after she lost 30lbs

Teen Mom's Tyler Baltierra took to Instagram Sunday to praise his spouse Catelynn Lowell after she lost 30 lbs.

'Can we just take a moment to acknowledge how beautiful my wife is!?' the Mount Clemens, Michigan native, 34, captioned the shot.

He added, 'She’s down 30lbs & I’m so beyond proud of her! I love you babe @catelynnmtv & you’re always the most beautiful to me!'

Baltierra added the hashtags #MyBabe, #Soulmate, #Queen and #SexyWitch in the Halloween-related posts.

The reality star posted a before and after shot of Lowell as she wore a witch costume over multiple years for Halloween.

Baltierra on Saturday shared a series of shots from the family's Halloween celebration as he and Lowell, 34, were posed with their children.

'HAPPY HALLOWEEN from The Baltierras!' he wrote, as he dressed up as the DC character Nightwing.

Their daughter Novalee, 11, dressed as Stick Man; daughter Vaeda, seven, dressed as It's Pennywise; and Rya, four, followed her mom's lead, dressing as a witch. Baltierra and Lowell also welcomed daughter Carly, 17, who they placed up for adoption.

A number of fans commented on Baltierra's post praising Lowell, with some noting that she has given birth to four children.

'Having one baby is hard,' said one user. 'Two, even harder to find yourself whatever that may be, but 4 babies!! Way to go!! You look amazing!!! Great supportive partner?! Even better.'

Another said Lowell is her 'favorite,' adding, 'she's beautiful kind hearted [and] heyy the girl created 4 amazing children our bodies do amazing things [and] they [don't] all fit one size.'

Other comments included, 'Once a baddie, always a baddie' and 'Well done Catelynn, beautiful always.'

One user said, 'She’s so beautiful. Always has been, always will be. Her soul is the gorgeous part too.'

Lowell, appearing on the podcast Virtual Reali-Tea in 2023, made clear she was not comfortable with body-shaming, saying that a remark Baltierra had made on Teen Mom OG in 2016 had been taken 'so out of context.'

In the episode, Lowell said that she had debated about signing on for a weight-loss plan, to which Baltierra responded, 'It’s your body, you can do what you want. I mean, obviously, I don’t want no heifer for a wife.'

On the podcast, Lowell said that if she 'was ever being body-shamed or called out of my name in front of my kids' by a partner, she 'would be gone' from the relationship.

She added, 'I don't want my children to think that that's okay to be treated like that.'

Baltierra himself over the years has posted shots to his social media pages documenting his fitness and weight loss regimen. 

The couple, best known for appearing on the MTV shows 16 and Pregnant and Teen Mom OG, celebrated their 11-year wedding anniversary this past August 22.
