Inside the Grammy After Parties

The Grammy Award fun got started early this weekend, starting with Clive Davis' premiere star-studded bash.

From a glamorous Katharine McPhee, decked out in Eli Saab, to a ravishing Carrie Underwood who rocked Naim Caan, there was no shortage of star power.

While music was the name of the party game, there was one person who was queen of the Grammy party night: a radiant Whitney Houston.

Draped in cashmere, a glowing Whitney made her red carpet comeback in stunning Cavalli style.

Also on hand for the festivities was Davis' newest darling, and Oscar favorite, Jennifer Hudson, who belted it out on stage.

A gorgeous Beyoncé rocked the Sony BMG party in a stunning black Robert Cavalli frock, her fourth outfit change of the Grammy night, before hitting the People magazine bash at new L.A. hotspot Eleven where the “Dreamgirl” gave us a preview of what to expect come Academy Award night.

“I can't give too much away; I will be performing with Jennifer and Jamie Foxx… that's all I can say,” Beyoncé dished.

Music's biggest weekend also turned into a love fest for Tom, Katie and Queen O, who all rocked the night away with Mary J. Blige at her private party.

“I feel the love, I definitely feel the love,” Blige admitted.

Meanwhile, across town at the Verizon Wireless-Rolling Stone soiree, Justin Timberlake brought “SexyBack” with “Extra's” own Mark McGrath!
