In spite of the promising title, Kevin Smith's newest movie Zack and Miri Make a Porno goes light on the porno. Only XXX star Katie Morgan dared to go naked in the flick, but as it turns out, that's not what was originally in the script.

Former princess of porn Traci Lords, who has a large role is Zack and Miri, recently revealed that her character Bubbles was supposed to have a topless scene, but Traci refused . . . because her milktacular rack was lactating!

According to IMDb, Traci shares:

"There was a scene where my character Bubbles was topless and I remember saying to Kevin, 'Listen, I understand why she's topless, but I'm lactating and if you want me, my boobs are off limits right now.'

"I haven't done nudity since 1987, so I don't think I would have done it anyway... I really want people to focus on something besides my breasts. I think we've seen enough of those. Plus I want them to be remembered in their heyday."

Wrong, Traci. We most certainly have not seen enough of those. And those breasts in an inflated state of MILFy milkiness . . . sounds like their heyday is NOW!
