It’s the biggest weekend in Washington, second only perhaps to Inauguration, which you clever kids know from civics class only comes once every four years (and without as many brunches).

So, here it is, the best of the fetes, as we scour the tables at the Washington Hilton to find someone not represented by Bob Barnett.

BEST OUTREACH BY A GOVERNMENT OFFICIAL

Obama Chief of Staff Rahm Emanuel. No one walks in LA, but apparently Hollywood hottie and “Entourage” star Adrian Grenier was making his way on foot to the Bloomberg/Vanity Fair after party when he was spotted by none other than Rahm Emanuel. The White House Chief of Staff’s brother, Ari Emanuel, was the inspiration for the high-strung, heavyweight agent portrayed by Jeremy Piven on the hit HBO show “Entourage.”

Rahm immediately had his motorcade pull over and Adrian hopped in. Now that’s taking it to the people!

BEST CELEBRITY BOOKING

FOX News’ Greta Van Susteren and John Coale, for not only getting reality star Kim Kardashian but for also not bragging about it. Technophile Greta photographed Kim’s every move and introduction on every red carpet (there were plenty).

NOT REPRESENTED BY BOB BARNETT

Kim Kardashian, but it’s only a matter of time. They did seem to enjoy a nice chat at the WHC Garden Brunch.

GREATEST ACT OF KINDNESS

Tony Romo. While at the MSNBC after party, the Dallas Cowboys Quarterback made a call to Chris Olson, brother-in-law of Politico’s Sara Olson as he recovered from emergency surgery in the hospital. Sara’s hubby Eric and Chris LOVE the Cowboys, so he approached Romo with the request – as you can see in this photo he jumped right in.

BEST WASHINGTON SPORTS FAN

Dan Pfeiffer, White House Communications Director. Pfeiffer initially refused a shooter from Dallas Cowboys QB Tony Romo exclaiming, “I am a Redskins fan,” while at the Friday night New Yorker party at the W.

MOST GRACIOUS GUESTS

The Jonas Brothers and family. Washington felt the loss of communications guru Carolyn Weyforth to this multitalented group but each member of the family is so engaging we can’t hold a grudge, especially after watching the family sign and smile for thousands of political and media fans.

BEST BUDS

The three amigos: actors Matthew Morrison of “Glee”, Chace Crawford of “Gossip Girl”, and Joe Mazzello of HBO’s “The Pacific”. Hundreds of hearts throbbed and cameras snapped as this trio of young stars were seen all over town from Café Milano to the Capitol. They also made many a Mom proud when they jumped on stage at the WHC Garden Brunch to help raise awareness for Mothers Day Every Day and CURE Epilepsy. Awww.

BEST NETWORK ANCHOR MOMENT

Morgan Freeman and Katie Couric. He not only lends his voice to the “CBS Evening News” intro, but Morgan Freeman offered up his hands to massage anchor Katie Couric’s tootsies at the Bloomberg/Vanity Fair party. Now that’s networking!

BEST TABLE GIFT

POLITICO.  Their guests found ebony BlackBerry covers imprinted with the bright red POLITICO logo waiting for them on their tables at the dinner. The covers are examples of sleek and simple branding, and quite handy.

BEST BOLDFACE FASHION

Kim Kardashian for wearing her mom’s vintage Valentino bought in Paris in 1984.  And Newsweek’s Jon Meacham for wearing JPress and telling POLITICO about it.

MOST WANTED RETURN GUEST – FEMALE

Candice Crawford, the former Miss Missouri and sister of People‘s Hottest Bachelor 2009 Chace Crawford…and girlfriend of Tony Romo. There are plenty of fellas in DC who would welcome her back sans her hunky beau (but you can bring Chace back with you, if you like).

MOST WANTED RETURN GUEST – MALE

Bradley Cooper, star of “The Hangover” and the upcoming remake of “The A-Team,” made his second appearance at the WHCA Dinner this year. We’re hoping that the Georgetown U grad (and one of People’s Most Beautiful 2010) will make it a hat trick.

BEST NEW EVENT

Robert and Elena Allbritton’s Politico Sunday Brunch.  An elegant civilized way to wrap up the weekend and say good-bye to new friends.

BEST PILLOWS

Bloomberg/Vanity Fair party swag were plush white pillows printed with fun quotable presidential quotes. Film ingénues Rosario Dawson and Anna Kendrick were seen smiling over this one:

Blessed are the young, for they shall inherit the national debt.

- Herbert Hoover

BEST RED CARPET MASH-UP

The Jonas Brothers and Texas oil and gas executive/energy independence commando T. Boone Pickens at the WHC Garden Brunch.

COOLEST WASHINGTONIANS

Carol Blue and Christopher Hitchens: the only two people who could stand in the middle of a Vanity Fair party and not look around to see who was there.

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.
