Christina Aguilera flaunted her slim body during an appearance on "The Tonight Show With Jay Leno" on Wednesday, September 18. The coach of "The Voice" wore a low-cut little black dress on the show. She had a curly blonde bob haircut and sported red lipstick.

On the late-night talk show, she talked about her return to "The Voice" as well as her previous interview with Maxim magazine, saying that going back to the singing competition was like "like coming back to school. The boys are fun!"

Christina apparently always had fun with fellow coaches Blake Shelton, Adam Levine and Cee-Lo on set. "There's something about the four of us getting together. We can't be serious for more than 30 seconds. The guys make me laugh!" she said.

Christina previously had an interview with Maxim, telling the men's magazine, "The one place I don't need to be in control is in the bedroom." When Jay Leno asked her to explain more about the statement, the "Let There Be Love" singer replied, "I'm a big micromanager. I'm a stickler about organization: everything needs a place, a purpose... I think every woman should relax and allow herself to be pleased in the bedroom. It's the one place I can let go."

Jay also asked her to elaborate on her statement which read, "I've never been one to shy away from my sexuality." Christina said, "I'm an artist, and expressing myself in a sexual way, no matter how that changes throughout the years, is something that has always come naturally to me. At this point of my life, I'm 32 and I feel sexier than ever because you know what you want."
