Christina Aguilera looks amazing all the time, but lately she's looked better than ever with a new svelte figure and toned down makeup (well, toned down for her!). And her fellow faces of 'The Voice' have noticed ... especially host Carson Daly, who made a comment about her bod that may well be inappropriate, though he meant well. We think.

Daly and the judges -- Aguilera, Adam Levine, Cee Lo Green and Blake Shelton -- were on hand to talk about their non-'Voice' projects, how it feels to return to the NBC juggernaut and other innocuous topics. When asked how it feels to be back on the series after taking a break (during which she was replaced by Shakira), Aguilera replied, "You know, it's a lot of stagnant energy sitting in a chair for three years, and I was excited at the chance I got to finally have a break to spend time with my son and do things that fulfill me. Honestly, I feel like when you get a moment to just breathe, and experience life, especially as an artist, it's hard to sit down and not be an artist for a while and not be a mom."

She added, "It's life, you know, just being able to breathe and have time away [from] the camera to get to the nitty gritty of all things real and personal and appreciate life so you come back refreshed."

Just then Daly chimed in with a comment about Xtina's ample chest. "You look incredible," the onetime 'TRL' host blurted. "We appreciate you kept your boobs."

Visibly uncomfortable but trying her best to play it off, a flustered Aguilera stammered, "Oh. My. God. Some things never change."

But maybe they should!
