Britney Spears posts completely nude photo on Instagram

Britney Spears is getting our attention again!

The "Toxic" singer posted a completely nude photo on her Instagram account late on Sunday night to help ring in the upcoming week.

In the black and white snap, Brit is covering her ladybits with one arm and with the other, she seductively has her hand placed near her face. Spears isn't wearing anything in the photo except several necklaces. She also clearly has a glam application of makeup.

While the photo seems to be from an old photo shoot, it's impossible to tell what Britney was trying to convey here -- other than she's 100 percent sexy. The 35-year-old singer has been no stranger to flaunting her hot body lately. She's recently posted tons of photos of her workout regimen and her rock-hard abs.

Keep up the good work, Britney.
