Christina Aguilera Costume: Flaunts Curvaceous Figure in Sexy, Revealing Halloween Ensemble [PHOTOS]

Pop star Christina Aguilera flaunted her curvaceous figure in a skin-tight, eye-popping costume at a Halloween-themed bash in Beverly Hills on Saturday (Oct. 27). The 31-year-old songstress looked very Nick Minaj-esque with a poofy, pick-and-purple wig topped with a tiara - but what really turned heads was her hip-hugging, cleavage boosting black dress embellished with a bright orange bra, sheer fishnet stockings, and some killer knee-high boots.

Aguilera hosted the spooktacular event at her L.A. pad on Saturday - check out the "Lotus" songstress rock her skimpy Halloween getup here.

Not exactly sure what the costume actually is, but it's fun to look at!

It looks like Aguilera's neon ta-tas really stole the show. A snapshot of "The Voice" star smooching hubby Matt Rutler (dressed as Aguilera's "knight in shining armor") shows the duo having a fun time celebrating Halloween in-style.

Some critics have bashed the "Your Body" songstress for her recent weight-gain, calling her "fat" and publishing other rude remarks. But Aguilera ignores all the negative tabloids, and quite frankly she looked great in her sexy Halloween costume (and extremely happy, nonetheless!). "The Voice" co-star Adam Levine has even come to Aguilera's defense, telling reporters in NYC on Friday: "People shouldn't say those kind of things, because, f-k you! Come on guys, grow up! It pisses me off, and of course I have her back, of course I defend her. It's not nice to just have your bread and butter be trashing other people. That's bullying."
