For your analysis, here is a picture of Kim Kardashian on Sunday night at PURE nightclub.  They look happy, right?  Then, why on Monday did they announce their split?

The pair, who recently returned from a charity trip to Africa with Kardashian’s sister Khloe, just last May talked about “heading” toward marriage, but sources tell PEOPLE their relationship suffered from the time they spent apart – with yet another separation looming with the upcoming NFL season. 

“They never get to see each other, ever,” the source says. “It’s been a long time coming. They still love each other and are part of their lives, but Reggie spends six months out of the year in New Orleans, so it’s tough.” 

I don’t know.  This looks like they had a, “Baby, I’ve got somethin’ to tell you” conversation after the nightclub appearance.  Kim’s rep confirmed the split, so I think either a)  she got dumped or b)  he admitted to cheating on her.

Pictures in the gallery of the couple at several events over the past couple weeks, displaying some interesting body language.

On the tail of things not workingout too well for Christina Ricci, comes news that Kim Kardashian and Reggie Bush are newly engaged. 

Kim was talking earlier this month about picking out her own ring.  “It’s just easier.  Isn’t it easy if someone’s like, ‘This is exactly what I want.’ It’ll make your life so easy.”  Now, some people are dead-set against knowing what their engagement ring looks like ahead of time, but my theory is this:  Kim’s going to have this ring on her hand for the next three to five years of her life.  Shouldn’t she have one that she really likes?

Now that Kim has officially hooked her boyfriend of the past two years, it’s time for her to get her butt moving and start shopping for a size two wedding dress.  Heh.

Kim Kardashian and Reggie Bush chilled out together at the “The Horrors” party at Sundance.

So far Kim and Paris have managed not to be at the same party together. I wonder if they’ll both show up at the 50 Cent show tonight …
