UPDATE: Oops, it's not her.

So who had the balls to send Chris Brown a three-page sext message while he's seriously dating a 5'8" Barbadian warrior princess? That's what everyone is asking now that the Los Angeles police report of Brown's violent brawl with Rihanna have been made public. Apparently, the heinous spat started when Rihanna read the extended message on Brown's not-smart phone. So, who is this biatch? Let us investigate.

On a fan forum over at Chris Brown World, a post made on January 8 -- more than a month before the blow-up -- was titled "What are y'all's feelings tworads [sic] Nikki?[Chris' ex-girlfriend]". It referred to another fan who wrote a post titled "I'm Unidentified a.k.a. Chris's ex girlfriend." After scouring for minutes through endless archives, we uncovered this video on a Lupe Fiasco blog of a pretty young thing named Nikki Jean sitting next to her "friend" Chris Brown and wishing him a happy 19th birthday. Jean is a sometime singer, sometime actress, and regular video blogger who was featured on Fiasco's album The Cool; she also toured with Kanye West on his "Glow in the Dark" tour. And yes, Rihanna was also on said tour, meaning so was Chris Brown. Jean displays early tendencies of using Chris Brown to make others jealous by proclaiming, "I just want to take advantage of this opportunity to make my little cousins super jealous!" Then, perhaps most tellingly, when Jean asks Brown if he has anything to tell her fans, Brown interrupts himself by looking into the camera, and saying "She fine!" Then, like a man who truly has no idea that in a few months he'll be ruined, he reminisces on the great year he had and how he was able to "maintain a great career and a great fan base." Not for long, Chris.

This is all speculation of course, and if you're not the vixen wedged herself between R n' B royalty, then we apologize. Because most likely, it was this nut below.
