Jennifer Hudson sparkles during Christmas in Washington event

Jennifer Hudson was decked out in a beautiful, sparkling gown at the Christmas in Washington event this past Sunday.

The singer and actress wore a gown designed by Pamella Rolland. The taupe-colored gown had subtle crystals all over it. The silhouette was both simple and flattering as it hugged her curves with a deep V-neckline. She paired the gown with dazzling bracelets on both wrists and her engagement ring shining on her left hand. She left a necklace out but wore studded earrings to bring the look together.

It wasn't only her dress and beautiful jewelry that stunned the audience, but also her fantastic and moving performance during the event.

Victoria Justice also shined during the festivities, as she wore a red BCBGMaxAzria gown with a simple sparking necklace and ring. Her long brown hair hung in loose curls. Justice also performed along with The Band Perry, Justin Bieber and Cee Lo Green.

The event, which was hosted by Conan O'Brien, took place at the National Building Museum in Washington D.C.
