(Cover) - EN Showbiz - Kim Kardashian and Miles Austin split because their relationship wasnt realistic.

The reality television star began dating American football star Miles Austin earlier this year, following the end of her romance with Reggie Bush. The pair have remained tight-lipped about the relationship, with both keen to keep out of the spotlight.

News they had parted ways began to leak over the weekend, and it has now been reported they ended things after deciding they were both too busy to make it work.

They split a little over a week ago, a source told E! News. It was mutual. It was because of their lack of time spent together and busy schedules. It just wasn't realistic that they could make it work.

Kim travelled to Europe last week, and it was shortly before she left that they decided to call it quits.

Her friends are now said to be encouraging her to romance a different kind of man when she is ready to date again. Reggie was also an American football star, and those close to the 29-year-old think she is more likely to find love with someone who isnt a sportsman.

She needs to date a businessman, a friend said. Athletes just aren't a good long-term investment. (C) Cover Media
