Kim Kardashian promises to stay single throughout 2011. Kim vowed to make the next year different from 2010 which saw her break up with Reggie Bush and Miles Austin.

"I want to try to be single my whole year of being 30," Kardashian says on The Rachael Ray Show.

"I've never just dated and done whatever I wanted."

The reality star says that her job had put a strain on her relationships. Previously, it was reported that Kim broke up with Miles Austin because their schedules have been keeping them apart and Kim wanted to focus more on her job.

"I have a hundred different jobs -- when do I have time to really focus on someone?" said Kim, although this might be a bit off from what reports had been saying.

Kim has been recently linked to Halle Berry's ex Gabriel Aubry. According to reports, Kim and Aubry spent Thaksgiving together at her mother's house Kris Jenner.

"I've made a promise to myself and I'm really trying hard to stick to it, but I'm such a hopeless romantic that it's hard," she explains.

"I don't think that's going to last, because that's just how I am. But the fact that I'm trying is a big step for me!"

But her work ethics did pay off for this year. Kim was the top earning reality star for year 2010, raking in an income of $6 million. She and her sisters have also opened the third branch of retail store DASH in New York City.
