LONDON, Nov 21 — Madonna is confused by nudity on social networks.

The pop veteran appeared to be commenting on Kim Kardashian’s recent nude shoot for Paper magazine with a post on Twitter yesterday.

In the message, Madonna admitted she is still unsure as to what is considered acceptable on Internet sites, when topless pictures are censored.

“Its confusing. Nipples are considered forbidden and provocative but exposing you’re a*s is not. #flummoxed (sic),” Madonna wrote.

Madonna’s tweet came after Kim admitted the shoot for Paper magazine, which saw her attempt to “Break the internet” by showing off her famous derriere, was a “token” before she gets pregnant with her second child.

“I have an even better body after having the baby than I did before,” Kim said during an interview on Australia’s 2Day FM. “I’m very confident about my body. It was just a little token before I have to go through pregnancy again.”

Kim also revealed during her trip to Australia that she hadn’t told mother and momager Kris Jenner about the nature of the shoot.

“She does manage me, but I’m pretty in control of my career,” Kim said. “Everyone thinks she’s this mastermind and tells us what to do and where to go.”

“She was actually in Paris with me and I had dinner with her right after the shoot, and I’m pretty private about the stuff that I do until it comes out,” she continued. “So I told her I did a shoot and I was like ‘Just wait until it comes out — you’ll see!’” — Cover Media
