Kim Kardashian stripped down to nothing but a white teeny bikini as she walks along the shoreline of a beach, exactly six months to the day since she gave birth to her daughter, North West.

“Kim feels confident again,” a source told Us Weekly. “She worked really hard and is so motivated to stay fit.”

“I am very frustrated today seeing reports that I got surgery to lose my baby weight!” she tweeted. “This is FALSE. I worked so hard to train myself to eat right & healthy, I work out so hard & this was such a challenge for me but I did it!!! I’m so proud of my accomplishment & NO ONE will take this away from me with fake reports! Say what u want about me but I work hard & am the most disciplined person u will ever meet!
