Badly beaten Rihanna was recording a song on a 'cheating partner'

Prior to getting badly bruised by an alleged attack by Chris Brown, pop star Rihanna had been recording a song about killing a cheating partner, which has leaked on the internet.

The Umbrella hitmaker had teamed up with rapper AKON for the track, called Emergency Room, which tells the saga of a woman seeking revenge from her unfaithful man.

The song further reveals about the woman's intention of removing the intravenous drip of her hospitalized man, reports The Sun.

The song's lyrics leaked on the internet are as follows:  I'm going to leave your heart broken on the floor/ You're gonna be in the emergency room/ I'm standing by your bed/ And so tempted to pull out your IV.

"Tryin' to call a nurse but nobody can help you now/ Let me see you try to live without me/ Now where's your heartbeat?/ Flatline on the ECG. I gotta say I found this a bit shockin'/ It's on receipts to tell you went shoppin'/ You bought some Nike shoes. But why you buying stockings?"

The Umbrella hitmaker was allegedly attacked by Chris Brown in their car, after they got into a heated argument over a text message from other woman, after which she was left with a split lip, a bloody nose and bite marks on her hands.

After fleeing the crime scene, Brown later surrendered to police and was charged on suspicion of making criminal threats.

He was later released on 35,000 pound bail.

Meanwhile, Brown's former step-father recently claimed that he "wouldn't be surprised" if the popstar had assaulted Rihanna.
