The 'Umbrella' singer - who was left battered and bruised after her ex-boyfriend attacked her in February at a pre-Grammys party – says she had convinced herself it wouldn't happen again and wanted to give their relationship another go.

She told US TV show 'Good Morning America': "I was so far in love, so unconditional that I went back. It's humiliating to say this happened. To accept that? It's a traumatising experience.

"I stayed. I even went back after he beat me, which was wrong. But again ... I'm a human being, and people put me on a very unrealistic pedestal. And all these expectations, I'm not perfect. Also it's pretty natural for that to be the first reaction. ... It's completely normal to go back. You start lying to yourself. The minute the physical wounds go away you want this thing to go away. This is a memory you don't want to have ever again."

Meanwhile, Chris blames his lack of anger management on the attack but still couldn't believe he had assaulted her.

He said: 'My thoughts are like, 'Why did it happen?' Like, 'What was I thinking? What is wrong with you?' That's what I'm thinking with myself.

'That's what my thoughts are, basically, now."

Chris attacked Rihanna in his car as they left a pre-Grammy Awards party in February, repeatedly punching her in the face and biting her arms.

He pleaded guilty to assault and in August was sentenced to six months of community service, 12 months of domestic violence counselling and five years probation.

The judge also issued a restraining order which requires him to stay at least 100 yards from Rihanna for five years.
