Kim Kardashian and Reggie Bush have been having very long telephone conversations and have been exchanging text messages.

The Miami Dolphins running back, who is currently very single at the moment, has been a shoulder to cry on for his ex-girlfriend, Kim Kardashian, who is going through a very public divorce from NBA star, Kris Humphries.

"The two have been talking for long periods of time on their cell phones and exchanging text messages. Reggie feels bad for Kim and everything she is going through right now. Reggie had been dating someone that he thought he could get serious with, but he ended that a few months ago. Reggie has absolutely no plans on getting back together with Kim. He just doesn't think they are meant to be together," a source close to the former couple revealed.

On Sunday night's episode of Kourtney & Kim Take New York, Kim, knowing her marriage to Kris Humphries was doomed, bared her soul to mother Kris Jenner during a car ride on a business trip to Dubai.

The former couple "fought constantly over Kim's quest for fame. Reggie is much more private than Kim and didn't want to be a part of the Kardashian-Jenner reality shows. Yes, Reggie did appear on a few episodes, but that was after much goading, and a lot of tears from Kim. It's truly sad because Reggie and Kim did love each other so much. Reggie didn't watch Kim's wedding special, but had that been him, he NEVER would have agreed to have his wedding filmed for a reality show," the insider says.
