X17 XCLUSIVE - Is THIS Chris Brown's Other Woman?

After those Paris Hilton rumors, it was recently reported that Chris' manager Tina Davis was the "mystery woman" who texted him on the night of his infamous fight with Rihanna. Davis was rumored to be romantically involved with the 19-year-old singer, but her lawyer has issued a statement denying any inappropriate relationship, saying, "The relationship between Ms. Davis and Mr. Brown is that of manager and client. There has never been any other relationship. The rumors in circulation are false." Soooo...it totally makes sense that we should be looking for a new mystery girl that Chris "had a previous sexual relationship with," right? Well look no further...our source confirms Tina Davis' statement and tells us, "Chris was NOT cheating on Rihanna with his manager. For the record, the girl's name is Natasha Ellie." We did a little bit of research, and as it turns out, Natasha is a stunning 27-year-old model living in Los Angeles, and she's done everything from sexy photo shoots to legit runway work to yup, you guessed it - R&B videos. The self proclaimed "Haitian sensation" has appeared in vids for R. Kelly, 112 and Akon, and she has been spotted on the Hollywood, Miami and Las Vegas party scenes. And Natasha Ellie is NOT to be confused with the 19-year-old singer Natasha, with whom Chris recorded a duet called "Fire" last year. Our source tells us exclusively that Chris had been fooling around with Natasha, and this has been an ongoing thing:

"Rihanna has been having problems with this girl for a long time. Rihanna even reached out to Natasha, [but she] denied everything. Have you heard the song 'Emergency Room' by Rihanna? In the lyrics she mentions finding Natasha's number in Chris' jeans. Rihanna didn't write the song, but she met with the songwriter and told her how she felt and what she was going though and they came up with it."

Our source added that as soon as the song came out, Chris was furious, but there was nothing he could do about it. So how does the song go?

I was pickin' up your clothes in the closet / I was bout' to throw your jeans in the washer / 'Til I saw a piece of paper sayin' "Tasha" / I gotta say I found this a bit shockin' / And some reciepts here that say you went shoppin' / You bought some Nike shoes / But why you buyin stockings? / Boy how could you lie to me? / I thought you would die for me / I'm not accepting another apology.

Well that sounds pretty damning! So what does Natasha have to say about this? We spoke to a rep for the model, and though she denies any sort of relationship between her client and Chris, she did confirm that the two met in Miami two years ago. The rep said that Chris was shooting a video, and he approached Natasha, seemingly wanting her to appear in one of his videos, but nothing materialized further. Or did it? Our source is very close to Rihanna (he spoke to her last night), and now that we know Natasha and Chris have met, we're finding it pretty hard to believe that these two weren't involved at some point. So, based on everything we just found out, what do you think? Is this the girl who sent the text that started the biggest news story of 2009??? We can't believe Rihanna would put up with this!
