Joanna Krupa strips for naked selfie to prove she's 'all natural'

If anyone thought Joanna Krupa was fake, then they'd be wrong!

And the not-so-shy former Real Housewives Of Miami star proved it by stripping off for a daring belfie (that's butt selfie for those of you who don't know).

In the eye-popping snap, the 37-year-old beauty was topless and in nothing but a G-string which showed off her pert behind.

"Mirror mirror on the wall... Good morning. #loveyourself #health #fitness #confidence #saynotohate #allnatural," she captioned the photo posted to Instagram.

It seems the post was VERY popular, as it received over 33,000 likes!

It's not the first time the Polish native - who is married to 43-year-old nightclub owner Romain Zago - has stripped off.

The model has posted a host of pictures of herself in her underwear lately.

But now it seems Ms Krupa is vying for Kim Kardahian's belfie crown.....
