Veggie VIPs Rock US Postage Stamps; Madonna First Female VIP to Rock Superbowl

Several VIPs (that's Very Important Potheads) will grace US Postage Stamps as part of a new series honoring "vegetarian icons" picked by PETA. McCartney (again) joins Woody Harrelson (natch), Chrissie Hynde, Natalie Portman and Pythagoras on the stamps, which are due to go on sale later this month.

It's just been announced that Hynde will open a vegan restaurant in Los Angeles along with Ellen DeGeneris, another of the 20 vegetarians to get a stamp. (Ellen's never admitted to smoking it, but joked about it when she hosted the Oscars in 2007.) Hynde's "Legalise Me" is the theme song in the new VIP video.

It's a good bet some of the other top vegetarians also toked. Pamela Anderson wrote a letter to Obama in 2008 in favor of legalization. Joan Jett covered the trippy 60s song "Crimson and Clover" and thought pot-puffing actress Kristen Stewart did a great job portraying her in a 2010 biopic. Leo Tolstoy explored the use of hashish and other intoxicants in his 1890 temperance essay "Why People Become Intoxicated," but his conclusions seem based on his experiences with wine and tobacco.

Lots of other cannabis connoisseurs have been honored with postage stamps, including Bessie Smith, Bob Hope, and Mark Twain, whose stamp came out this year. Also given a stamp in 2011 was pioneering African-American writer and filmmaker Oscar Micheaux, in whose 1931 film "The Exile" VIP Louise Cook appeared.

And it's been announced that Madonna will appear at this year's Superbowl halftime show on Feb. 5.

As well as turning a suburban spa salesman onto pot in her 1985 movie "Desperately Seeking Susan," the world's most successful female musician admitted to smoking pot and taking Ecstasy in March 2008 upon her induction into the Rock and Roll Hall of Fame.

The Material Girl (worth an estimated $325 million) is far from the only pot lover who's appeared at America's biggest sports fest. Tom Petty and the Heartbreakers rocked the stadium in 2008. At Superbowl 2005, Paul Mc Cartney played "Get Back" with the lyric, "Jo Jo left his home in Tucson Arizona, for some California grass." In 2004, Willie Nelson played along with country singer Toby Keith, he of the famed tune, "I'll Never Smoke Weed With Willie Again."

At least one member of last year's halftime act, The Black Eyed Peas, is a known pot smoker: rapper Taboo (né Jaime Luis Gomez) was arrested near LA in March 2007 after marijuana was found in his car. The Peas just appeared at the nation's tree-lighting ceremony along with Kermit the "It's Not Easy Being Green" Frog and President Obama.
