Happy 33rd birthday, Christina Aguilera! You celebrated in the way most people only dream of celebrating: onstage with Lady Gaga in matching iridescent-gold chiffon outfits and blonder-than-blonde hair. While Lady Gaga's performance was expected, Christina joining for a Sweeney Sisters-esque duet was most certainly not.

Lady Gaga kicked off the performance in a lamé, billowy sleeved jumpsuit and a platinum 'do reminiscent of her "Paparazzi" days. Then, like a moth to a glittery flame, Xtina emerged in a matching high-slit dress.

The dazzling duo held hands triumphantly and canoodled before trying to out-riff each other. Though matching in metallic material and platinum hair, Christina stood apart from her disco sister with a curly, Donna Summer-inspired 'do.

The final touch (and confirmation that the duo are no longer feuding) was a champagne toast followed by smashing the glasses. Who cares if there's glass everywhere?? Xtina and Gaga are BFF!! Congrats on making up, you two! You could take that Dreamgirls act on the road and wear different lamé outfits every night!

Watch the gilded jumpsuit and dress in all their glory here!

No matter who you were rooting for throughout this premiere season of NBC's "The Voice," style-philes across the country no doubt became smitten with runner-up Dia Frampton. Her totally unassuming sweet-as-pie demeanor was balanced by crazy-insane vocals (THAT TONE?! Don't get me started. I just. I'm obsessed, OK?) and a killer fashion sense. Or at least what has blossomed into such. As you mayyy or may not know, Dia wasn't always the old-Hollywood-channeling besequined glamourpuss you see above. *dun dun DUNNN* (BEETEEDUBS: Dia's coach, Blake Shelton, and his wife, Miranda Lambert, totally bought that dress for her AWWW!!!)

I love these two as a couple. What a festive way to celebrate two important events in their life. Mariah looks like a dream.
