AceShowbiz - Maralee Nichols treated her followers to a new photo of her and Tristan Thompson's son Theo. The fitness instructor shared the picture of her and her young kid giving a sweet surprise to a friend.

In the Saturday, September 7 snap, Theo could be seen holding a bouquet of flowers as he stood outside of a door. The 2-year-old looked adorable in a white T-shirt and a mini backpack. He also sported a black bucket hat featuring yellow smiley faces.

It seemed like the photo was taken when the mom and son duo gave a birthday surprise to Maralee's friend. She wrote over the snap, "Happy Birthday surprise for @stephaniejean___ We love you!! [heart emoji]."

The post came shortly after Tristan posted a photo of him posing with his other son, Prince. In his post, the NBA star shared a carousel of pics with Prince whom he shares with ex Jordan Craig. The picture saw the Cleveland Cavaliers star and his eldest son standing on the sidewalk in front of a home.

For the occasion, the 7-year-old boy wore a gray Essentials T-shirt and sweatpants, white Nike Air Force 1 sneakers and a backpack. As for Tristan, the athlete rocked a black Jordan sweatsuit set and matched shoes with his son.

After initially denying to be the father of Theo, Tristan confirmed his paternity in January 2022. At the time, he wrote, "Today, paternity test results reveal that I fathered a child with Maralee Nichols. I take full responsibility for my actions. Now that paternity has been established I look forward to amicably raising our son."

He additionally issued an apology to ex and baby mama Khloe Kardashian, saying that she didn't deserve the "heartache and humiliation" he caused her.

In addition to Theo and Prince, Tristan is a father to daughter Tatum (6) and son Tatum (2) whom he shares with Khloe.
