"Theo, my little angel baby. I named you Theo because it means, 'Gift from God.' 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," Nichols shared with ET. "I love you more than you’ll ever know. You bring such joy and happiness into my life. My greatest blessing."
Nichols and Thompson were in a prolonged legal battle regarding the NBA star's paternity, until a paternity test proved him to be Theo's father back in January. Thompson is also the father to 5-year-old son Prince, whom he shares with Jordan Craig, and 4-year-old daughter True, whom he shares with Khloe Kardashian.
