Kourtney Kardashian has let slip who the new partner is in her younger sister, Kim Kardashian's life.

"She's dating her work," Kourtney jokingly said (according to People.com), "Kim is a workaholic."

Kourtney then went on to say that all she wants is for her sister to be happy, and at the moment the socialite seems to be feeling just that with her current beau, Dallas Cowboys' Miles Austin.

She said; "[Kim] is having fun. I don't think she's found that perfect person for her yet. Everything happens for a reason, like Khloe [Kardashian] and Lamar [Odom]. One second you meet someone, and you're married a month later. You never know. There is no time limit. Not everyone meets their perfect person at the same age."

That doesn't sound like good news for Miles. Yikes!
