The woman's identity wasn't revealed nor was the name of the San Antonio Spurs player. A source tells PEOPLE the woman was actually the wife of a former, not current, teammate.
Longoria, 35, filed for divorce on Wednesday amid reports that Parker, 28, cheated on her. The divorce petition cites "irreconcilable differences" and Longoria is seeking spousal support.
Longoria says that Parker cheated on her earlier in their marriage and that he kept in touch with the woman on Facebook, according to Lopez.
"She is devastated, she wants us all to know that," Lopez says. "But she's strong."
