Maralee Nichols posted photos of her and Tristan Thompson’s 2-year-old son, Theo — as the NBA star celebrated his and Khloé Kardashian’s son Tatum’s 2nd birthday.
The fitness model shared pictures on her Instagram Stories on Sunday of her little one heading to a beach while riding in a stroller wagon with sand toys.
In a second post, Nichols held Theo’s hand as he looked at the ocean waves with his feet in the water. She also shared a video of the toddler running in the sand.

The personal trainer notably documented the outing while Thompson, 33, attended his ex Kardashian‘s lavish dinosaur-themed party for their son Tatum’s 2nd birthday.
The extravagant gathering was decked out with multicolored balloon arrangements, life-size dinosaur sculptures and pool floats.
Guests — including Tatum’s aunt Kim Kardashian and his grandmother Kris Jenner — dined on cookies, Rice Krispies Treats, tortilla chips and guacamole, burgers, fries, chicken nuggets and fruit cut into dinosaur shapes.
The Cleveland Cavaliers player, who also shares daughter True, 6, with the Good American co-founder, shared a sweet birthday shout-out to his son on Instagram.
“Happy birthday Tatum!! Man time goes by so fast! I can’t believe you’re already two years old!” he captioned his post.
“I am so blessed and honored to be your dad. Your energy and charisma lights up the room. Thank you for being such an amazing son and brother to your mommy and sister. Watching you grow every day makes my heart happy. Continue being the angel you are son. Daddy loves you so much.”
Nichols gave birth to Theo in December 2021, just one month after Kardashian, 40, conceived her and Thompson’s second baby together via surrogate.
The NBA champ initially denied being Theo’s father but took to Instagram in January 2022 to confirm his paternity.
“Today, paternity test results reveal that I fathered a child with Maralee Nichols,” he wrote at the time. “I take full responsibility for my actions. Now that paternity has been established I look forward to amicably raising our son.”
Thompson also issued an apology to the “Kardashians” star, whom he was dating when Theo was conceived.
The athlete, who does not post Theo on social media and has not been seen publicly with the toddler, has since agreed to pay Nichols $10,000 per month in child support. He was ordered in March to backpay her $58,000.
Thompson is also a dad to son Prince, 7, whom he shares with ex Jordan Craig.
