TRISTAN Thompson's baby mama, Maralee Nichols, has celebrated their son, Theo's first birthday with a lavish bash.
The fitness trainer took to her Instagram Stories to share photos and videos from the tot's special day.
In one photo, Maralee posed with the birthday boy in front of a massive blue, white, and silver balloon display and a huge baby blue sign decorated with white snowflakes.
On the sign were the words "Theo's Winter ONEderland" in cursive writing - a play of words to honor Theo turning one.
With her son in her arms, Maralee stood in the center donning a white long-sleeved dress, knee-high silver boots, and her long brunette locks flowing down.
Theo appeared to sport white shorts and a blue jacket with his eyes glued on the display behind them.

The photo also showed two clear cases on either side of them - one holding a stand filled with sweet treats decorated with baby blue icing.
The other case held a two-tier cake decorated similarly to their backdrop with a trail of balloons down the side, keeping with the color scheme.
Maralee gave a closer look at the dessert in the following clip, showing three adorable white bears on the cake, including one that held the number 1 at the top.
The baby blue cake also had Theo's name spelled out in silver lettering in the center.

The youngster seemed to enjoy his big day as his mother also shared a snap of him sitting in his new toy car.
In the pic, Theo gripped the steering wheel of the black convertible with an orange interior wrapped with a giant white bow on the front.
Maralee filmed the sweet moment from above, hiding the little one's face from the camera.
WINDER WONDERLAND
Elsewhere in her Stories, Maralee showed off more photos and videos from her only child's birthday celebrations.
In one clip, she showcased a bundle of blue, white, and silver balloons positioned along the stairwell of her Los Angeles home.
Beneath the display was a pink Christmas tree decorated with white lights, silver ornaments, and a white tree skirt.
The proud mom played the Happy Birthday song in the background as the words were displayed on the screen.
In the next snap, Maralee highlighted the cookies she ordered to match the Winter Wonderland theme, including cutouts of teddy bears and penguins dressed in snow gear.
Other cookie shapes were pastel-colored Christmas trees, snowflakes, the number one with snowflakes painted on them, and personalized treats with his name on them.
The festivities continued with a walk through an outdoor lights display featuring lit-up butterflies, rhinos, flowers, and lights along the trees.
Maralee posted a photo of her holding Theo outside the attraction where the words "Joy" and "Love" illuminated in bright lights.
The 31-year-old kissed her baby boy, who was sporting a puffy coat, while she wore a white jacket, blue jeans, and knee-high white boots.
BIRTHDAY LOVE
Earlier in the day, Tristan's baby mama commemorated their son's December 1st birth date with a series of photos of the duo.
She kicked off her post with a photo of herself breastfeeding Theo.
Maralee captioned the pic: "My baby is 1 today."
She posted a series of snaps on her Instagram grid as well.
The first photo in of three showed Maralee wearing all white as she posed, holding her son to stand.
His back was to the camera, and he had on only a diaper with tulle wrapped around him.
A second photo showed Maralee alone in the same tulle outfit, this time showing off a baby bump.
It's unclear if that photo was taken prior to Theo's birth or recently, and it got fans buzzing about another potential pregnancy.
A third photo showed her hanging from a sheer swing, again showing off a bump.
She did not respond to the pregnancy speculation in her comments, nor did she reply to the commenters wishing Theo a happy birthday.
In her caption, she wrote: "I can not believe you are already one. Spending the past 365 days with you have been the best days of my life. You are the sweetest little boy, your smile brightens up any room.
"You are my greatest blessing, my world, my heart in human form. God knew I needed you. I love you more than anything. Happy 1st birthday to my angel, Theo."
SILENT DAD
However, Tristan did not publicly acknowledge his baby son's birthday and remained quiet on social media.
It has been reported that the athlete has not met his son and is not a part of his life.
News that Tristan, 31, fathered a child with Maralee broke just before she gave birth to their son.
The NBA star was supposedly in an exclusive relationship with Khloe Kardashian, 38, at the time, and the pair were preparing to welcome their second child via surrogate.
