One of those events is the annual WHCD Garden Brunch. In 2009, hundreds of guests gathered in the garden, but there was a twist. The brunch was given in honor of the Mother’s Day Every Day campaign and featured honorary brunch Chair Ann Curry of the Today Show, with special guest Susan Axelrod of CURE Epilepsy.

Mothers Day Every Day is a U.S. advocacy group for maternal health led by the White Ribbon Alliance and CARE. Their campaign for healthy moms and newborns aims to raise the political will and resources to reduce maternal mortality around the world to meet the United Nation’s Millennium Development Goal number five.

There were some incredible moments as Captain Richard Phillips, who survived the Somali pirate attack, met Homeland Security Chief Janet Napolitano and relived his dramatic rescue for the first time.  T. Boone Pickens and his wife Madeleine talked to reporters about their successful campaigns for the Pickens Plan and to save wild mustangs

And “Gossip Girl” star Chace Crawford taped a Mothers Day greeting surrounded by the star-stuck, pre-teen girls volunteering at the brunch. Arriving guests loved the adorable girls who greeted them with white ribbons, which were tied around their wrists in honor of mothers everywhere.

Since the garden brunch’s start 17 years ago, when Barbra Streisand made a surprise guest appearance, Hollywood stars in town for the dinner have made the Saturday morning event part of their itinerary.  Last year’s star power included Kerry Washington, Ludacris (escorting his own lovely mother), Christian Slater, Val Kilmer, Matthew Modine, Tim Daly and Dana Delany.

Washington’s own stars—Ben Bradlee, Sally Quinn, Andrea Mitchell, John King, David Gregory, Betsy Fischer, Greta Van Susteren and John Coale, Luke Russert, Gordon Peterson and Norah O’Donnell—turned out in force to mingle with the year’s top newsmakers: Todd Palin, Alan Greenspan, and Rep. John Dingell.  Last, but not least, there was a who’s who from the Obama administration in the crowd: Austan and Robyn Goolesbee, Mona Sutphen, Melody Barnes, Bill Burton and Katie McCormick Lelyveld.

Media and opinion leaders from around the country gathered including Newsweek’s Jon Meacham, Time’s Richard Stengel, Arianna Huffington, and Walter Issacson. And L.A. media mogul and agent provocateur Andrew Breitbart brought father-in-law Orson Bean, a crowd favorite.  Politico’s Mike Allen posed with nephews and fans while reporters swarmed Val Kilmer to ask whether he would make a run for governor.

This year’s brunch will again honor the Mothers Day Every Day campaign, which is led by advisory committee co-chairs Donna Shalala and Ann Veneman, and co-founders Dr. Helene Gayle and Theresa Shaver. WHCInsider will supply live coverage on Saturday, May 1st, as the first guests arrive.

It’s sure to draw another stellar “cast” of characters who will enjoy a morning drink and conversation with expected—and unexpected—guests. The spring blossoms, the fun, and the gossip, are sure to get everyone in the mood for the White House Correspondents Dinner on that evening.

Guests included actors Val Kilmer, Christian Slater, Matthew Modine and Dana Delaney; Capt. Richard Phillips of the Alabama Maersk and his wife Andrea; Homeland Security Secretary Janet Napolitano; former Clinton administration official Donna Shalala; David Gregory, Andrea Mitchell and Ann Curry of NBC News, and many others.

The party ran from Noon until 3:00 p.m., when guests started leaving to prepare for tonight’s big event.

In addition to Kutcher and Moore, CNN will be bringing actors Val Kilmer, Kyra Sedgwick, Bradley Cooper and supermodel-turned-talk-show-host Tyra Banks. But anchor Wolf Blitzer has invited a local bold-faced name — Homeland Security Secretary Janet Napolitano.
