Teen Mom fans claim Catelynn Lowell 'couldn't look any better' as she shows off her weight loss in rare full

TEEN Mom Catelynn Lowell has shocked fans with her changed appearance in a new video with her daughter, Rya.

The MTV star took to Instagram on Tuesday to share a sweet clip of her with her youngest daughter.

In the clip, Catelynn held the two-year-old as they danced in the kitchen to the Luke Combs remake of Tracy Chapman's hit song, Fast Car.

Rya seemed to love the bonding moment and rested her head on her mother's shoulder while Catelynn sang the words in her ear.

The young mom gushed in her caption: "Excuse the way I look BUT I love moments like this with Rya we dance and I sing to her motherhood is HARD but times like this make it ALL worth it."

Fans praised the mom of three - who sported tight black shorts and a blue and gray T-shirt - in the comments for her looks in the video.

Catelynn has been working hard in the gym in an effort to lose weight, and many have taken notice of her results.

"You look like a safe, comfortable, loving mommy. I think you look beautiful," one person wrote.

"What's this talk of 'excuse the way I look' you look beautiful always! That sweet girl loves her mama dancing with her and we love it too!" another remarked.

"Never apologize for the way you look!! You are beautiful no matter what but especially when you are being an amazing mom!" echoed a third.

A slew of others had similar comments, with some saying the young mom "couldn't look any better."

Catelynn previously gave fans a glimpse at her workout in a video taken by her personal trainer, Torrez Training.

In the clip, the TV personality rested on a Powermaster, with her legs grounded on the tilted base and her arms bent with her hands holding on to handles near her head.

Two heavy-looking weights sat for her to push on top of the moveable part of the machine.

The 31-year-old squatted up and down, with her face twisting with the exertion of the task.

Her trainer captioned the video: "@catelynnmtv leg day," with two sunglass-wearing emojis.

He also revealed she was "down four lbs in two weeks."

Catelynn shared the video on her own Story and added a relatable sticker of a woman looking tired while lifting a weight.

Catelynn's husband, Tyler Baltierra, has also shown off his weight loss achievements.

Last year, he posted a photo revealing his toned torso and muscular arms after dramatically changing his figure.

In the comments, one fan praised: "Bro! Post your workout routine I need to up my game."

In August, Tyler, 31, revealed in more detail how he achieved his impressive weight drop without losing his strength.

The gym fanatic revealed that he had shed 24 pounds in five months in impressive before-and-after photos.

Catelynn is often proud to show off her handsome husband on social media.

In one post, she bragged: "Look at my man. He's like a fine wine - gets better and better with age!"

Catelynn and Tyler are middle school sweethearts who've been documenting their journey as parents on the Teen Mom franchise.

In addition to Rya, they share daughters Novalee, eight, and Vaeda, four.

They are also the biological parents of a 14-year-old daughter, Carly, whom they placed for adoption as a baby.
