Disgusting : This is what Chris Brown did to Rihanna!

Chris Brown is such a loser. Hitting a woman! No excuse!

But Rihanna is stupid too.....forgiving him...sigh..what is she thinking?

This is apparently what Chris Brown did to her according to search warrant on the case and detective notes taken by Det. De Shon Andrew.

Rihanna, 21, read a three-page text message from a woman on Brown's phone, which led to an argument. Brown allegedly tried to force his girlfriend out of the Lamborghini, and hit her head against the passenger window.

Rihanna then "turned to face Brown and he punched her in the left eye with his right hand,". He then drove away in the vehicle and continued to punch her in the face with his right hand while steering the vehicle with his left hand."

Blood filled Rihanna's mouth. Brown, 19, allegedly told her, "I'm going to beat the s--- out of you when we get home. You wait and see!" Rihanna called her assistant and left a message saying, "I am on my way home. Make sure the cops are there when I get there."

The police notes say that prompted Brown to reply: "You just did the stupidest thing ever. Now I'm really going to kill you."

The report also says that Brown bit Rihanna and put her in a headlock, and that she almost lost consciousness. "Brown resumed punching [Rihanna] and she interlocked her fingers behind her head and brought her elbows forward to protect her face," according to the notes. "She then bent over at the waist, placing her elbows and face near her lap in attempt to protect her face and head from the barrage of punches being levied upon her by Brown."

Eventually, Rihanna began screaming for help and Brown got out of the car, according to the notes. A nearby resident heard the calls for help and called 911.

After all THAT, the couple reunited in Miami Beach 3 weeks later. Sigh Sigh Sigh!!
