The Keeping Up With The Kardashians star, who is currently dating the hip-hop mogul, says hearing the Chicago rapper’s tracks on the way to an early morning work-out is a sign of good things, and motivates her fitness regime.

“My gym is 15 minutes away, so I get in the car and listen to the radio,” explained the 31-year-old.

“If a song by my boyfriend comes on, I know it’s going to be a good day.”

Kardashian, who has regularly been snapped with beau Kanye in fitness gear, also revealed that when travelling to the gym solo, she doesn’t mess about.

“I’ll be at the gym by 7am, work out for an hour, run for 20 minutes on the treadmill, then go straight home,” said Kim.

Her workout’s certainly pay off, as the star, who is known for her killer curves and famous derriere, also revealed her healthy eating regime to British magazine More!

“I try to eat healthily so I have gluten and sugar-free meals, if I can. I never drink coffee, and breakfast will be on one of the freezer packs, so all I have to do is heat it. I love plain, simple food like an egg-white omelette. For a treat, I might have a little taste of mom’s home-made frozen yoghurt.”
