Christina Aguilera showed off her slim figure on The Tonight Show with Jay Leno on Wednesday night, telling the late night talk show host that she feels better than ever.

The Voice mentor wore a figure-hugging black dress with a pair of sexy Christian Louboutin heels and she gushed about her self-confidence.

"At this point of my life, I'm 32 and I feel sexier than ever because you know what you want,” she said, E! Online reports.

She added, "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."

Leno asked the mother of one to elaborate on a quote she gave to Maxim when she posed seductively on the cover recently.

She said what she meant by "the one place I don't need to be in control is in the bedroom,” is that is the only place she can really “let go.”

"I'm a big micromanager,” she explained. “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."

Aguilera has been dating her boyfriend Matthew Rutler for almost three years, and she said of her son Max with ex-husband Jordan Bratman he’s “the joy of my life.”
