Kim’s extreme nude shoot prep S

He’s been naked so often, there can’t be that many people left who haven’t seen Kim Kardashian in her birthday suit. But she’s planning to strip off again – and heat can reveal she’s going to extreme lengths to make sure she has her best body yet. “Kim wa

in yet another naked photo shoot. She’s shed all the baby weight and is ready to go totally nude,” an insider tells us. “She’s posed in provocative scenarios many times before, but this time she wants something really wild – some sexy boudoir shots, like in Madonna’s Sex book. She wants it to be shocking, but tasteful.”

But, in order to have the confidence to bare all, Kim, 36, has been putting herself through a gruelling overhaul. The reality star was left devastated when unairbrushed pictures of her famous bottom emerged while she was on holiday in Mexico in April, but these have now spurred her on.

“Kim has never been this motivated in her life. After those pictures of her bikini body came out, she wanted to crawl under a rock,” an insider reveals. “Kim’s obsessed with dropping more weight and won’t eat more than 700 calories a day. She eats an egg white and blueberries for breakfast, some field greens for lunch, and dinner might be a few strips of sashimi and broccoli. On top of that, she’s punishing herself with intense workouts. She’s pinned up the photos of her butt from earlier this year as inspiration.”

After giving birth to North, four, and 19-month-old Saint, Kim struggled to shift the pounds. But now that she and husband Kanye West have decided to use a surrogate for their third child, she won’t have to worry about gaining weight, so she’s focused on making herself perfect. But it’s not just dieting helping her achieve her new look. “Kim hit rock bottom a few months ago and needed to do something about it. Surgery is always her answer and she has recently undergone a number of figure-sculpting ops, including a boob lift, lipo, upper-arm “fat freezing”, knee tightening and a butt boost,” our insider adds. “She’s mainly focused on her butt and wants to overhaul it. She’s obsessed, and also wants more Botox, fillers and laser treatments, which will end up setting her back around $500k. “Kim has worked hard to transform her body. Now, she’s finally feeling good in her own skin again and she wants to celebrate it.”
