Kim Kardashian is on a "mission" to garner a fabulous post-split body.

The reality TV beauty is famed for her short-lived marriage to Kris Humphries, which lasted just 72 days before they announced they had split.

Kim is now eager to impress with her looks now she's not attached.

"I'm on a mission," she told US Weekly at a recent event. "I figure, I'm single. Now is the best time to get in shape."

Kim who revealed she trains with brother Rob - added that her gorgeous figure is the result of working out two times a day, "morning treadmill runs and strength training or Pilates at night."

The 31-year-old star also admitted that she's changed her diet habits. The raven-haired model is more pro-active about her health and fitness regime.

"No more sitting at home, eating too much!" she quipped.

Kim has come under intense scrutiny for her brief union with Kris. She is ready for the storm to pass.

"I'm so ready, emotionally, for this to be over," she said.

Kim discussed her personal life on the Tonight Show with Jay Leno last week, and although she didn't mention Kris directly, the beauty admitted that she still believes in fairy-tale endings.

"I learnt so much, and the things I care about in my life have completely changed," she said of the high-profile break-up. "I still believe in love. I'm in love with love. I thought this was it for me."
