Christina Aguilera at AMAs: Fuller-Figured Songstress Sparks Twitter Outcry and Social Media Weight Debate [VIDEO]

Christina Aguilera took the stage at Sunday evening's 40th annual American Music Awards to perform a combo of three of her newest singles, "Lotus," "Army of Me," and "Let there be Love." But it wasn't the pop songstress' killer vocals or unique fashion sense that really turned heads this time - instead, it was her much fuller-bodied figure that sparked an outcry on Twitter, leading to a heated social media debate on the 31-year-old's ever-fluctuating weight. Aguilera rocked a star-studded black body suit and sleek platinum blonde do' during her AMAs performance, but it was what lied underneath the costume guise that had fans talking on Twitter. Some people harshly criticized Aguilera's recent weight gain, while others found the songstress completely gorgeous and amazing. So what do Mstarz readers think?

Before taking the stage in her funky star-studded ensemble, Aguilera hit the Red Carpet decked out in a flowing, multi-purple colored dress that highlighted her very curvaceous figure. Some Twitter fans loved it... others, not so much (many critics placed Xtina on their "Worst Dressed" list). Even though Aguilera's performance was meant to send a message of acceptance and love, there are still some harsh haters out there (but with just as many supporters!). Check it out:

@iamToddyTickles: "Did Christina Aguilera eat one of Willy Wonka's blueberries? #AMA."

‏ @Christina_VIP: "Love @TheRealXtina! Her music has soul, passion and most importantly a message! So proud to be a #Fighter!"

@Luvvie: "Carrie Underwood is what Christina Aguilera thinks she looks like right now. And no one has the heart to tell her "NAWL."

@TheBlondsNY: "XTINA SERVED US EXACTLY WHAT WE ORDERED TONIGHT. SENDING A MESSAGE OF LOVE, ACCEPTANCE & OWNING YOUR TRUTH. <3 @TheRealXtina."

‏@ShannSantagato: "Christina Aguilera looks like Snooki. No wait, that's an insult to Snooki."

@TheNickyParis: "The awkward moment when Christina Aguilera can't fit in her Genie Bottle anymore...."

@AndreaRussett: "anyone who says Christina Aguilera isnt amazing can leave nearest exit to the left thanks."

@ohheydaniel_: "what happened to christina aguilera o m g."

@LanceBass: "New hairstyle and looking gorgeous! Christina Aguilera aka Legendtina Godulara! #AMAs."

@thatgrapejuice: "There is hilarious irony in the fact that those dragging Christina Aguilera's weight aren't a work of art themselves #AMAs..."

@_Jimmy_BIGGZ: "calling Christina Aguilera and Adele fat is dumb.. they still sing better than 90% of the artists out there."

‏@changetopics: "I'm old enough to remember when there was space between Christina Aguilera's thighs."

@AllieMcGev: "Christina Aguilera looked gorgeous last night. I love this dress and the diva attitude she is serving!"
