New court documents have revealed alleged text messages exchanged between Paul Pierce and his ex-girlfriend, Princess Santiago, as the two continue their legal dispute over custody and child support for their infant son.

According to the filing obtained by TMZ, Santiago said she informed Pierce shortly after the child’s birth.

“I just wanted to let you know that your son is here. He was born today. If you’d like to see him tomorrow, let me know,” one alleged message read.

After reportedly receiving no response, Santiago later sent another message criticizing Pierce’s lack of involvement.

“I gave you so many chances to do the right thing and not have to go down this path … you’re letting history repeat itself, acting just like your father. My son will not be ignored or treated like the black sheep.”

According to the filing, Pierce later acknowledged paternity after receiving test results.

“Just found out today officially that’s my son so anyway I can at least see him,” an alleged April text from Pierce stated.

Santiago responded by saying Pierce had multiple opportunities to establish paternity before the child’s birth.

“Hello and congratulations, Paul. 99.99%. Anyway, you had the opportunity to take the test I paid for either before or after the birth. Instead, you chose not to and ignored my entire pregnancy with him; you prioritized love interests, vacations, other people and things over your son.”

The filing also states that Santiago later told Pierce she would no longer pressure him to become involved.

“If you want to be a father to him, cool. If not, I’m not going to beg you.”

Santiago is seeking sole legal and physical custody of their son, along with child support. She also alleges Pierce has not fully disclosed his financial information and has had limited involvement in the child’s life.
