A text message sent by Chris Brown's manager and rumoured former lover sparked his altercation with girlfriend Rihanna, according to internet reports.
Brown has been charged with assault and making criminal threats after an allegedly violent argument with the singer on the night of 8 February (09).
The Umbrella hitmaker was reportedly left with cuts and bruises and needed medical attention for her injuries.
According to TMZ.com, Tina Davis - who was rumoured to have had a romantic relationship with Brown when he was 16 - sent the singer a lengthy text message on his cell phone during the night in question, sparking a row between the couple.
An affidavit by a detective investigating the case allegedly refers to the text message as being "from a woman who Brown had a previous sexual relationship with", while law enforcement sources claim the message to the shamed R&B star proposed a meeting for a late-night rendez-vous.
Davis, 40, and Brown, 19, have both denied the affair.
The Kiss Kiss singer is free on $50,000 (£36,100) bail after he was granted a continuance at his arraignment hearing last week (05Mar09). He is due back in court in April (09).
If convicted, Brown faces up to four years and eight months behind bars.
