For reference, this is Heidi at a UNICEF event in Boston the night before, with "Project Runway" co-star Tim Gunn.

Back on Friday night at Heidi's, Ashanti took over a table like royalty.

Coco and Ice-T made the scene.

The hardcore boxing trainer who trains Wall St. wussy guys (his words, not mine) Eric Kelly. You may remember him from a viral video that launched a flood of incoming reality TV offers.

The scene at Heidi's.  She got Svedka vodka and Moto X to sponsor her bash, now in its 15th year.

There were sort-of costumes at amfAR's mega bash on Wednesday night.

Not Justin Timberlake’s first time riding shotgun on a semi-bedazzled and exposed nipple in public. This time, Rihanna took the honors at the amfAR Inspiration Gala that raised over $3 million at Milk Studios. Belvedere vodka kept the cash flowing.

Another look at Rihanna's style. 

Meanwhile in more traditional party gear, British Ambassador Sir Peter Westmacott came from Washington, D.C. to Thursday night’s Britannia Awards.  He joined one of his own, Dame Judi Dench, at the Beverly Hilton proving the concept behind the “GREAT Britain” campaign.
