Tekashi 6ix9ine's baby mama says he didn't just embarrass himself by getting jumped at the gym ... he embarrassed his daughter, too.
Sara Molina, through her rep, tells TMZ ... Tekashi's very public altercations have been sad to see, adding their seven-year-old daughter, Saraiyah, will eventually see the ways he's acted when she grows up.
Although he did nothing wrong when he was beaten at an L.A. Fitness, Sara believes he was reckless by not having security, especially given his history of public altercations.
