According to US Weekly, the 32-year-old performer, who judges the music show with Blake Shelton, CeeLo Green and Adam Levine, flaunted her tighter body on Monday.

Aguilera, with her svelte frame, teamed up with rapper, Flo Rida to perform their new single, "How I Feel." The songbird had slipped into a sheer bodysuit before taking the mic.

At the start of her performance, the platinum blonde rocked a low-cut black blazer, rhinestone nude tights and black top hat. But midway through the song, however, she removed her blazer. Underneath the jacket, she had on an ultra-sexy, sheer bodysuit that exposed her black bedazzled bra and tiny shorts underneath.

"Looking confident and better than ever, Aguilera strutted across the stage while belting out her hit song," reported US's Nicole Eggenberger.

Aguilera spent her season off from the show gettting into great shape.

"It's more of a mind-body thing for her," said a source previously to US about the singer's workout and diet plan. "She believes in exercise that she enjoys, doing strength work as opposed to intense cardio."

And Aguilera's fellow "The Voice" mentor, Levine thinks her hard work has paid off.

"...She looks great, she feels great," said the Maroon 5 singer on "The Tonight Show with Jay Leno" on Oct. 28. "Also, we all know each other better so our chemistry on the show sort of improved."
