Miss: Chris Brown a woman beater?

Sunday night, R&B's hottest couple, Chris Brown and Rihanna, were supposed to light up the Grammys. Instead, the normally affectionate twosome were embroiled in a domestic violence drama that left Brown, 19, booked on felony criminal threats charges and posting $50,000 bail after turning himself in to the LAPD on Sunday at 6:34 p.m. PST.

Sources say that Rihanna (real name: Robin Fenty), 20, was the victim in the alleged assault which occurred around 12:30 a.m. on Sunday. Responding to a 911 call about a disturbance, the LAPD took statements from a female with visible injuries, who named Brown as her attacker.

Rumored to be a couple towards the end of 2007, the singers were first photographed at the Grammys on Feb. 10, 2008. Often coy about their yearlong relationship, the two consistently refused to talk about their romance during interviews. But the pair offered up other signs of their closeness, from matching star tattoos on their necks to holding hands and kissing at concerts.

Even at the Clive Davis party at the Beverly Hills Hilton on Saturday night, Brown and Rihanna looked cozy and happy. But over recent weeks, they seemed to have hit a bumpy patch in their relationship. "They've been fighting a lot lately," a source told PEOPLE. "Lots of ups and downs. One second they're all lovey dovey and then they're fighting like crazy. They're both pretty stubborn."

One rumor has it that the fight was over Chris's infidelity. It's said that Chris got a phone call from a certain young woman, and Rihanna went off when she recognized the name and number. She started hitting him while he was driving and they hit a parked car. A police source confirms to PEOPLE that the singer suffered a black eye as well as "a swollen split lip and two red and purple contusions on either side of her forehead." For his sake let's just hope that those bruises were caused by the rumoured car accident and he didn't put his hands on a woman. Otherwise, that's very bad news for CB, can you imagine what they'll do to his pretty ass in an LA jail?

In theory you should reap what you sow, so if a woman puts her hands on a man, then he should be able to put his hands on her right back. In reality, that's just ugly. A man has nothing to prove by putting his hands on a woman. Everyone knows men are stronger physically. If you make a bad choice, and end up with a woman who doesn't know her boundaries, remove yourself from her vicinity -- permanently. By not doing that so, then beating her, you only prove that you are weaker mentally. And no matter how it started, you are now the culprit. Either way the truth of this istuation shall come to light soon, and judging by how much interest the media has been showing this case, a lot sooner then you'd think. To be continued....
