Taken aback by the revelation that Ozzy Osbourne is dabbling with a vegan diet? Keep reading. The following list of famous vegetarians from the past and present is filled with more surprises than a paternity test on Maury:

1. Steve Martin

As a comedian, actor, author, and musician, Steve Martin has a lot on his plate. But one thing you won't find on this "wild and crazy guy's" plate is meat. Which, of course, is the secret to having happy feet.

2. Susan B. Anthony

A pioneering feminist and suffragist who supported the 19th century animal welfare movement, Susan B. Anthony toasted both vegetarianism and women's rights at a banquet held by the first American Vegetarian Society. Anthony was also the first woman and only vegetarian to be immortalized on American currency.

3. Vincent Kartheiser 

For the love of Pete (Campbell), we wish that everyone would follow in the low-carbon footsteps of Mad Men's Vincent Kartheiser and ditch meat to help the environment.

4. Michael Imperioli

It's not only mad men who shun meat—wise guys fuhgeddabout flesh too. When asked about his favorite restaurant in Detroit, where he was filming a TV show, former Sopranos star Michael Imperioli named veggie hotspot Inn Season Café. "I'm a vegetarian, so [it's] like culinary nirvana for me."

5.  Fred Rogers

Fred Rogers was the man. Not only did the devout vegetarian teach kids about the joys of soy on Mister Rogers' Neighborhood, he also took Burger King to task for parodying him in a commercial. After he criticized the ads for being "very confusing for children," Burger King apologized and pulled the commercial. Can you say "coolest neighbor ever"? I knew you could.

6. Rosa Parks

Rosa Parks was the woman. The civil rights leader, whose refusal to give up her bus seat to a white passenger ignited the end of segregation, advocated vegetarianism. Active in promoting peace and justice well into her 80s, Parks credited her vegetarian diet with helping her to maintain her health and stamina. 

7. Harvey Levin

We hate to gossip, but a little bird who likes to tweet told us that Harvey Levin, the executive producer and host of hot celebrity gossip news show TMZ on TV is a vegetarian!

8.  Vanilla Ice

 And finally … stop, collaborate, and listen. Vanilla Ice is back with healthy intentions. High cholesterol grabbed a hold of him tightly. Now he feasts on veggies daily and nightly. Word to your mother (and to anyone who hasn't gone vegan yet).

OK, so we didn't get to see a song-and-dance number featuring Steve Martin and vegetarian Alec Baldwin—who also narrated PETA's now-classic documentary Meet Your Meat—but we're still pretty happy about how the highly buzzed Food Inc./Cove face-off turned out.

The Oscar for Best Documentary went to frontrunner The Cove—the universally acclaimed examination of Japan's bloody dolphin trade and slaughter. And in one of the most inspiring moments of the night, Ric O'Barry proved that he'll stop at nothing to end the slaughter by displaying a sign encouraging people to get active for dolphins during his acceptance speech.

The win couldn't have come at a better time for captive marine wildlife, as Sea World and other parks come under increasing scrutiny for their abysmal record of injuries and deaths of both trainers and animals in the wake of last month's incident at SeaWorld.

On the red carpet, The Cove's director Louie Psihoyos put it best when he said, "One animal killing three people in one lifetime shows these animals are stressed, they don't belong in captivity. And when we capture them out of the wild and force them to do stupid tricks for our amusement, it says more about our intelligence than it does theirs."
