SHE claimed she wasnt broke - but that was before California officials filed another federal tax lien against Pamela Anderson ... this time in the amount of $180,000. The new lien - filed last month - is the latest in the former Baywatch stars alleged tax troubles ... in fact, just last year, the State of California filed a separate tax lien against her for $493,144. Anderson responded to the 2009 lien last December saying she wasnt broke ... just disorganized - claiming, Mistakes may have been made in calculating taxes owed and we are now in the process of ensuring that any taxes owed are paid. Unfortunately, shes got no explanation this time around - calls to her rep werent returned. TMZ
