Paul Pierce's Father's Day took a dramatic turn after Princess Santiago publicly accused the basketball Hall of Famer of neglecting their baby boy.
In a series of Instagram posts on Sunday, Santiago unloaded on the former Celtics star, claiming he celebrated Father's Day online while failing to spend time with their infant son, King.
Her posts targeted a Father's Day tribute Pierce shared featuring four of his other children.
Santiago pointed out that King, who is nearly 5 months old, was absent from Pierce's plans despite it being the baby's first Father's Day.
She also alleged that Pierce has only seen the child twice since his birth. Santiago later doubled down in a since-deleted comment under one of Pierce's posts.
The social media outburst is the latest development in a contentious situation between the two.
As previously reported, Santiago filed a paternity lawsuit against Pierce in January while pregnant with King, seeking DNA testing to establish paternity.
She later requested sole custody of the child and nearly $30,000 per month in child support.
Pierce acknowledged he was King's biological father in court filings in April and requested joint legal and physical custody.
