Kim Kardashian is rumoured to be engaged to her American football star boyfriend Reggie Bush.

Sources close to the Keeping Up With the Kardashians star say the 22-year-old New Orleans Saints player proposed after they spent the festive period together.

Kim revealled at the Mansion's Tanqueray and Ciroc New Year's Bash she hosted in South Beach where Reggie was her date: "One thing I did learn from 2007 was to try to keep it as private as possible so I'm trying to hold that close to my heart but I'm here with everybody that I love.

"This holiday has been the best. I'm the best cook! People don't know that, but I cook all the time. My best dish is surprisingly my soul food meals - fried chicken, my macaroni and cheese and my sweet potato soufflé."

Meanwhile, the reality TV and sex tape star also revealed that we might see less of her famously curvy rear in 2008 - because she's going on a diet.

She confessed: "I'm giving up deep fried Oreos. There's nothing even remotely healthy about them, but they are 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."

She added to People magazine: "I need to start eating responsibly. It's time to eat right. I get enough exercise. My problem is that I eat crap.

"I'm not going to starve myself. I'll still treat myself now and then, but I want my basic diet to be healthier.

"I know what's good for me and what isn't. It's just a matter of making the right choices."
