Reality star Khloe Kardashian is flaunting her newly slim bod in a new interview with Life and Style magazine, saying she was tired of being the “funny, fat one.”

The youngest Kardashian gal, 25, says she took up a strict exercise routine and dropped 20 pounds so she could fit in better with her sexy sisters, known for their enviable figures.

Kardashian admitted to being teased as a young girl for her weight, which she says became an issue when she used food to ease her emotional pain from her parents divorce. Later, she developed an eating disorder at 15 before gaining 30 pounds of extra weight.

But these days, the young star is down 20 pounds in just four weeks and is “now a size six, but I’ve been up to a size 10 in the past.” She credits her sister Kim – who recently released a series of workout DVDs- for helping her stay on track.

FOXNews.com recently spotted Khloe looking svelte at a party in New York City, where her new bod was the talk of the night. But her new figure didn't help her social skills - the star spent the entire night texting and never once cracked a smile!
