LINDSAY LOHAN'S publicist Steve Honig has quit, but sources say it's not because of anything SHE'S done. It's because of her psycho dad, MICHAEL LOHAN. When Michael showed up at Lindsay's house for that supposed "intervention", he said Lindsay's team, including her lawyers and Steve, were behind him. Steve later released a statement saying they had nothing to do with it, and sources say Michael went ballistic on him . . . which was the last straw. But Steve issued a statement saying Michael isn't the only reason he quit . . . quote, "Michael wishes he were that important." He added, quote, "I'm not discussing this out of respect for my client."
