What's the first thing a 40-year-old mother-of-three thinks of doing while she's vacationing with her family in Italy? Most people: take the kids to get gelato; Kourtney Kardashian: post a nude selfie on Instagram!

KK stripped down for the sexy snap as she and her kids and friends vacationed in Sardinia, Italy over the past week. On land and on a yacht, Kourtney makes sure she shows off her bod for her 80 million Instagram followers in hopes of maybe cross-promoting her not-so-successful lifestyle brand Poosh.


In fact, Kourtney appears to be copying uber-successful half-sis Kylie Jenner in an effort to revive the brand. She's filed for "non-medicated skincare" trademarks for Poosh. If Kylie and Kim can do it, maybe Kourtney can too!

Kourt is copy-catting another famous lifestyle brand, it seem -- Gwyneth Paltrow's Goop. Clearly Kourt's look and feel, content and vibe on Poosh's dot-com mirror Goop. Even the name is similar! Still, the web site and it's in-house luxury label haven't taken off and a new report claims Kourtney blames momager Kris Jenner for the failure. RadarOnline reports, "Kourtney doesn’t understand why Poosh isn’t taking off like she was hoping, but she is blaming Kris. She thinks Kris has focused so much of her time and energy into Kylie and Kim, she completely neglected her." After all Kris has done for her girls!! Really?!
