With the way some in Hollywood have piled on Miss California Carrie Prejean since Sunday's Miss USA pageant, one might think the 21-year-old college student had called for a tax on botox, instead of speaking out against gay marriage.

First, Perez Hilton called her a "dumb [expletive]" in a self-produced video on his Web site.

Then Tinsletown took to Twitter, as the likes of Shanna Moakler, Giuliana Rancic, Holly Madison and Heidi Montag Tweeted their outrage.

Moakler, who is co-chair of the Miss California pageant, Twittered "I agree with Perez 100 [percent]."

E! News anchor Giuliana Rancic Twittered on Tuesday that "I know i'm a journalist, and i should be objective ... but she is an ignorant disgrace and she makes me sick to my stomach."

"[L]esbians should have the same government rights that Spencer and I will when we get married. So, yes, this blonde Christian believes in gay marriage," chimed in camera-chaser Heidi Montag. While Perez Hilton’s fellow Miss USA judge, "Girls Next Door" reality star and Playboy bunny Holly Madison, Twittered to Moakler right after the crowning, "[Y]ou did a great job tonight mama! where is the party now, cause I am so upset."

But Hollywood was just getting started.

On Tuesday celebrity comedy site FunnyorDie.com released a celebrity-laden web video spoofing America's so-called fear of "the gay marriage storm."

A slew of stars including Alicia Silverstone, Lance Bass, George Takei and Sophia Bush came together to parody "The Gathering Storm Ad," made by the National Organization for Marriage (NOM), which is against same-sex unions.

"I am afraid because I have a fear of storms," Silverstone says melodramatically. "I'm a Massachusetts mother helplessly standing by as the schools teach my children that gay marriage is okay. I also have an issue with their hot lunch program."

The sarcastic tension builds with the stars expressing their horror that "soon these gay people will start falling out of the sky ... Onto our homes, onto our churches and onto our families" as people suddenly start dropping onto the set from above.

The video's producer, Lauren Palmigiano, said the best way for them to make their message clear was through humor.

"We spent two days in our green screen barn shooting with all the actors. The editing and all that gay rain took a few more days to put together and there you have it," Palmigiano told FOXNews.com. "It's frustrating when people spread misinformation and sometimes the best way to combat it is with a joke. But the biggest joke in this whole debate is that somehow giving all couple equal rights affects anyone else's marriage."

Representatives for NOM responded to the ad Wednesday, telling FOXNews.com:

"While I haven't seen this particular parody, I have seen and enjoyed others; it’s important not to take yourself so seriously you can't take a good joke, and we appreciate how the controversy has helped spread our message." said Maggie Gallagher, President of the National Organization for Marriage.

"On a more serious note: the vitriolic response by Joe Solomonese and others mischaracterizing the millions of people who have these concerns expressed in our ad as ‘liars and bigots’ only tends to confirm our main message: same-sex marriage is not about tolerance, it’s about using the power of law to impose a new morality on an unwilling American people."

But the tide of public opinion may be turning in Prejean's favor.

Her grandmother has blasted her critics, especially Perez Hilton.

"I don't know why that gay guy Perez was even judging a contest with a bunch of girls. That doesn't make any sense. He should be judging a Chippendale's contest," Jeanette told RadarOnline.com.

And her state pageant co-chair Keith Lewis, who denounced Prejean immediately after Sunday's competition, has since softened his stance.

"I am proud of Carrie Prejean’s beauty and placement at the 2009 Miss USA Pageant. I support Carrie’s right to express her personal beliefs, even if they do not coincide with my own," Lewis said in a statement on Tuesday. "I believe the subject of gay marriage deserves a great deal more conversation in order to heal the divide it has created."
