Maralee Nichols, the mother of Tristan Thompson‘s youngest son, has revealed the boy’s name.

Theo Thompson was born on Dec. 1 in Santa Monica, California.

The NBA star’s name is not on his son’s birth certificate because he disputed his paternity when his son was born. Nichols also said Thompson’s “name was not on the birth certificate because he was not present at Theo’s birth.”

In an Instagram Story, Thompson confirmed that he fathered the child with the personal trainer, apparently during a one night stand in a Houston hotel last year.

Nichols, 31, explained the meaning behind her son’s name.

“Theo, my little angel baby. I named you Theo because it means, ‘Gift from God,'” Nichols said in a statement to PEOPLE Thursday.

“I had never been pregnant and had been told I might not be able to have children. I couldn’t believe I was pregnant, when I saw you on the ultrasound and heard your little heartbeat I knew I would always protect you and keep you safe. I love you more than you’ll ever know. You bring such joy and happiness into my life. My greatest blessing.”

Nichols’ rep told PEOPLE that Thompson has never met Theo, and he “has done nothing to support their son.”

“He has not made any attempt to meet their son nor has he provided any financial assistance,” it added. “In the future, we hope that reporters covering this situation contact us to confirm any facts before publishing.”
