"    Photo: Courtesy of NBC Last night Lady Gaga swapped her usual &amp;quot;Do What U Want&amp;quot; duet partner, R. Kelly, (too much bad press lately?) for Christina Aguilera, and the result was the performance of campy disco dreams. Who ever said divas can&amp;#039;t be friends? Gaga and Christina held hands, wore gold lam\u00E9 (so much lam\u00E9), sashayed through a cloud of smoke and swigged champagne through interlocked arms like drunk 22-year-olds. If you missed it on The Voice last night, you might not think you&amp;#039;re fully awake when you watch the clip, below. It&amp;#039;s kind of surreal. There&amp;#039;s even a Gaga-on-Aguilera boob nuzzle at the 2:51 mark. Really. Hey, everyone needs a bosom for a pillow.
