TEEN Mom OG star Catelynn Lowell celebrated her 30th birthday with a night out on the town, showing off her curves in a sexy look.
She and husband Tyler Baltierra share four children, one of whom they placed for adoption when they were teens.
On Saturday, Catelynn shared a series of photos from her birthday celebration.
The reality star struck a pose, holding two bottles of alcohol in her hands as she smiled for the camera.
Her curves stole the show as she was pictured wearing a dark red top with a deep V-neck.
She paired the top with a pair of leather-look pants and black boots.
In a second photo, the reality TV mom sipped from one of the bottles she was photographed holding.
A third photo showed her smiling for the camera, still holding two bottles in her hands.
She captioned the post: “30 and fine.”
Catelynn’s husband Tyler didn’t appear in the photos with her, though he did wish her a happy birthday.
Their children also were not in the photos, and it’s unclear if they were present.
THROWBACK
Tyler marked his high school sweetheart’s birthday with a series of photos of himself and her through the years.
His moving tribute highlighted the couple’s 15-year relationship which started when they were middle schoolers, saw them become teen parents and then carried through as they became reality stars.
Several of the snaps showed the lovebirds as youngsters.
Tyler paired the photos with a sweet message for his wife on her big day, writing: “HAPPY 30th BIRTHDAY to the most amazing woman, mother & wife. I love you more than I could ever express with words…but I love trying anyway 
”
He continued the post with a poem.
“It’s a mystery how you do it
Always pulling me up from ruins
Giving me strength to build a future
You’re the one that keeps me moving
You’re the lightning over the darkest seas
Your love like a beacon guiding the way
So I can forever feel safe
Even while the storm rages & I’m not okay
Your beautiful embrace is my sacred place
Your soul is in my bones that keep me strong
Your voice serenades reminding I belong
I want to get lost in your arms & live in the stars
Surfing the galaxy & surviving on dreams
With you next to me is where I want to lay
My fingers through your hair
& your head on my chest
is my favorite place to stay”
He concluded the post with: “Happy Birthday babe, I love you so much! @catelynnmtv 
#15YearsStrong#MiddleSchoolSweethearts“
Tyler and Catelynn both have had much to celebrate as of late.
Just weeks earlier, Tyler celebrated their daughter Vaeda turning three-years-old with sweet videos of the toddler.
The first showed the tiny tot riding in a wagon on Halloween wearing a unicorn costume.
She snacked on candy while riding around the neighborhood.
The reality star’s voice could be heard in the background, saying: “You’re already getting into your skittles aren’t ya?
“What are you eating? Num nums? What do ya got?” he inquired.
In a second video, Vaeda wore a puffy snowsuit, snowshoes, and pink gloves, as she played in freshly fallen snow.
She topped off her look with a rainbow beanie and bright pink bow.
Tyler could be heard saying “careful” as she made her way through a snowy pathway.
In the third clip, Vaeda munched on ice while getting buckled into her car seat.
She screamed: “Woo!” when a song began playing on the radio and smiled brightly for the camera.
Tyler captioned his post: “HAPPY 3rd BIRTHDAY my beautiful, spunky Vaeda beta butt!
“I feel so blessed every time I hear you say ‘Dada’ & I promise I won’t ever take that honor for granted!
#VaedaLuma.”
CAUSING CONCERN
Despite the upbeat posts, Tyler recently sparked concern from fans when he shared a dark poem on Instagram about fighting off “evil.”
In February, the MTV personality posted a black-and-white photo of himself posing in front of a mirror wearing a tight jacket, jeans, and dressy shoes.
He captioned the post with a poem about facing “evil,” which started: “Go ahead. Try to bury me. I prefer the dirt. For I am a seed.
The poem continued: “I’ll grow back fervently like weeds.
“Watch me take over with greens. Dominating roots underneath. My power comes from places you can’t see.
“Stretching into the earth so deep. My core is untouchable to your type of evil.
“So bring on the storms & let the rain pour.”
Tyler’s post ended: “That weather has always pushed me. To grow back stronger than I was before.”
The reality star included the hashtag: “#WritingIsHealing.”
