The singer reveals Brown was her "first big love"
Singer Rihanna is to talk for the first time about being assaulted by her ex-boyfriend Chris Brown in an interview being screened in the US this week.
The 21-year-old will tell ABC's Diane Sawyer what happened on the night of the attack in February, a statement from the TV network said.
Brown was sentenced to five years probation and six months community service in August over the attack.
The interview will be screened on Good Morning America on Thursday and Friday.
ABC said the singer reveals Brown was "definitely my first big love", but adds: "This happened to me - it can happen to anyone."
Rihanna was left bloody and bruised in the attack on the night of the Grammys.
During the interview she also talks about growing up in Barbados, her family life and how she has been over the past nine months since the assault.
Brown was interviewed by CNN's Larry King in September where he said he still loved Rihanna and was in shock over his actions.
