Christina Aguilera is having a good time showing off her figure ever since she slimmed down a few months ago. She lost 49 pounds after overhauling her diet and fitness routine.

On Tuesday, "The Voice" coach uploaded a selfie on Twitter with the caption: "Sneak peek! Feeling sexy & seductive on set with Mark Liddell filming…"

Aguilera is pictured lying down on a bed wearing a white body-hugging dress with a side cut out. Her tootsies are covered in sequined pumps. The singer points a camera at herself as she gives a sultry look.

She didn't reveal what the photo shoot was for.

The pop star has no problem showing off her curves. On Monday night's episode of the singing competition she rocked a black mini dress that showed off some cleavage.
