Christina Aguilera's looking hotter than ever these days!

On Wednesday, the slimmed-down, sexy star stopped by The Voice season 4 premiere screening in L.A. Wearing a form-fitting black dress with a studded belt, the newly svelte singer told E! News she's "always here to come back and support!"

And while the 32-year-old blond beauty won't be back in the fancy chairs this season, she's still very much a part of The Voice family, including Blake Shelton and Adam Levine (who admittedly are a lot to handle!).

"These boys are a lot to take on…in increments," she said with a smile. In fact, on Monday, Christina tweeted Blake and Adam a reminder to treat the Voice's newest judge, Shakira, "like a lady!"

"It's just the locker room environment," she explained. "It's constant testosterone. It's just constant boy, bathroom humor. It's a lot."

"But you know what?" she added. "I'm not worried about Shakira at all."

Neither are we!
