Don't believe rumors that Kim Kardashian is getting back together with NFL star Miles Austin. The Internet was abuzz with reports the two, who split in September, were reconciling after they swapped messages on Twitter last week. But a source tells us, "They are not getting back together, they are just friends. And she's not dating Kanye West, either." Meanwhile Kim, who opens her New York Dash clothing store with sister Kourtney this week, has been spending a lot of time with her bodyguard, Shengo Deane, who provided a romance storyline for her reality show. Her rep didn't get back to us.
