Kim Kardashian vows to diet - but keep curves in 2008

Kim Kardashian bid farewell to an old an favorite - the deep-fried Oreo, as she welcomed in the New Year.

While hosting a New Year's Eve party at her Mansion in Miami Beach, the 'Keeping Up With The Kardashians' star, 27, told People.com: "There's nothing even remotely healthy about that, but it's so, so good.

"I figured that I'd end 2007 with a bang and eat something really bad for me that I love. But beginning tomorrow, that's off limits."

Kardashian says that in 2008 she's going on a diet: "I need to start eating responsibly. It's time to eat right," she says.

Although Kardashian exercises regularly, she says her eating habits are her downfall. "I get enough exercise," she reveals. "My problem is that I eat like crap."

But she insists she won't lose her famous butt, saying: "I'm not going to starve myself.

"I'll still treat myself now and then, but I want my basic diet to be healthier."

During New Year's Eve, Kim spent the evening with her sisters, Khloe and Khourtney, as well as new boyfriend, NFL star Reggie Bush.

Although Kardashian doesn't have a specific diet plan in mind, she says she knows how to eat healthy. "I know what's good for me and what isn't," she says. "It's just a matter of making the right choices."
