Chris Brown cheated on Rihanna with a model.

The 19-year-old singer - who has been charged with felony assault and making criminal threats following his alleged assault of Rihanna last month - was having a relationship with 27-year-old brunette beauty Natasha Ellie.

It has been claimed Natasha sent the three-page text message - initially reported to be from someone who Chris "had a previous sexual relationship with" - which sparked Chris and Rihanna's argument, during which he allegedly punched, bit and choked the singer until she was unconscious.

A source said: "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."

'Emergency Room' includes the lyrics: "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."

Natasha lives in Los Angeles and has worked as a runway model and also starred in several R'n'B videos, for artists including R. Kelly and Akon.

Natasha's representative has denied the model had a relationship with Chris, but confirmed the pair met in Miami two years ago.
