With her hands strategically placed to cover her breasts, Christina - who donned a leopard print hat - took the topless selfie in a bathroom mirror.
Just days after Kim Kardashian's naked selfie, Christina has followed suit with her very own up close and personal snap.
Voice US coach Christina, said: "Just so you know with me, it's all real, all the time. Felt like it was time to start sharing some personal stuff with you guys... And it's just the beginning. Night night."

'Beautiful' singer Christina welcomed daughter Summer Rain with fiancé Matthew Rutler on 18 August. She is also mum to son Max, seven, from her relationship with ex-husband Jordan Bratman.
