Rihanna says she felt as if she had woken up as Britney Spears the day after Chris Brown assaulted her.

In an interview with US Glamour magazine, the 21-year-old singer spoke candidly about the media's reaction to the incident in February.

“I went to sleep as Rihanna and woke up as Britney Spears,” she said. “That was the level of media chaos that happened the next day.”

Rihanna was left with facial injuries after former boyfriend Brown assaulted her during an altercation in Los Angeles.

Rihanna talks about Chris Brown attack on ABC's Good Morning America.

Brown later pleaded guilty to assault and was sentenced to five years' probation and ordered to do community labour.

Rihanna said she hoped that her experience could shine a light on the threat of domestic violence that women face on a daily basis.

“The positive thing that has come out of my situation is that people can learn from that,” she said.

“I want to give as much insight as I can to young women, because I feel like I represent a voice that really isn’t heard.”

The singer also opened up about the attack during interviews for Good Morning America and 20/20, which air later this week.

The singer is currently preparing to release her new album, Rated R.
