Christina Aguilera gave her Facebook fans a glimpse of her amazing body when she posted a pic of her on-set filming a music video yesterday, and it's obvious the singer has undergone a massive slimdown!

The blonde bombshell rocked a black pencil skirt and a matching bustier as she struck a pose on a balcony overlooking the ocean, and all we have to say is her boyfriend is one lucky guy!

"I love my body. My boyfriend loves my body. My son is healthy and happy, so that's all that matters to me," the Grammy winner previously explained of her body confidence.

Maybe she's getting in tip top shape to look good on camera when she returns to The Voice next season!
