Kim Kardashian says she's "doing okay" following her split earlier this week from Reggie Bush, her NFL beau of more than two years. But speculation is running rampant over what went wrong for the couple, who many predicted would make an end-run for the altar.

The most civil explanation for the parting of ways comes courtesy of People magazine, which says their "conflicting career obligations" deep-sixed the romance.

"Reggie really wanted her in New Orleans when he was there playing but Kim is traveling more than ever," explains an insider of the "deeply ambitious" pair. "She has so much going on, it just wasn't physically possible for her to be there the entire season. With their schedules, it wasn't realistic anymore."

But there are also rumblings of less seemly reasons for why they called it quits, with accusations of eyebrow-raising behavior surfacing on both sides. According to FoxNews.com, the breakup was precipitated by a telecommunications-related "blowup."

"Reggie saw text messages on Kim's phone from Kanye West and flipped out on her," maintains a mole. "The texts referenced a night they hung out, how much fun he had, how hot Kim was, and more racy things that got Reggie's imagination running."

The source says the squabble illuminated "trust issues on both sides, and [they] couldn't go forward."

But RadarOnline.com points the finger at Bush. Seems a "sexy Latina model" in Miami is contending that she repeatedly got up close and personal with the gridiron star and has been hinting that she hopes to sell her supposedly salacious story to the highest tabloid bidder. Kardashian was said to be "furious" over the model's allegations.

However, insiders have insisted that no third parties were involved in the bust-up, so: Anyone else just want to go with the conflicting work schedules story and move on? Yeah, us too.
