What a difference a season off makes. Christina Aguilera, who took a hiatus from 'The Voice,' will be back this fall. And while she didn't tour in support of her album 'Lotus' (which tanked), she did use her time wisely: She got herself in incredible shape, looking better than she has in years.

Xtina has clearly shed the pounds, as evidenced by her visibly slimmer tummy, backside and lovely face. (So much for those BBW endorsement offers.)

The photo on the above right was taken in September of 2012, but in recent months, we've noticed her shrinking frame -- and this weekend, the body-con blush pink Alaia mini, nude Christian Louboutin heels and messy white blonde waves she sported at a 'Voice' promo event got everyone's attention. And for good reason.

Thankfully, she didn’t overdo it with bronzer or her signature crimson lips. Her Old Hollywood glam look has become her hallmark, but we prefer a lighter look on her. When paired with her baby blues, that glossy pink lip looks otherworldly.

Those legs! Welcome back, Xtina. (And hey, Adam Levine -- pretty sure you can stand down now.)
