Ashley and five of her friends got free tickets to attend last Thursday’s show . . . the one where PIA TOSCANO was shown the door. When the girls got there, three of her skinny friends were given sweet, front-row seats. But Ashley was not invited to join them. In fact, she says a staffer told her, quote, “Oh no, you’re just too big, too heavy to be in front!” Instead, she was assigned a seat in the very back row.
