Rihanna

Rihanna said she felt taken advantage of by her February 2009 altercation with Chris Brown and the resulting media storm it caused.

"I went to sleep as Rihanna and woke up as Britney Spears," the 21-year-old pop star said in a new interview with Glamour. After the assault, Rihanna endured not only a private emotional battle but also a public battle with press, which elevated when a police photo of her bruised face was leaked on the web. "It was humiliating ... I felt completely taken advantage of," she says. "I felt like people were making it into a fun topic on the Internet, and it's my life."

Rihanna said she leaned on her family, friends and her faith."At some point you are there alone. It's a lonely place to be — no one can understand," the songstress says. "That's when you get close to God."

Rihanna also discussed other positives that have emerged from the dark situation. "I'm stronger, wiser and more aware," she said. "You don't realize how much your decisions affect people you don't even know, like fans."

Chris Brown says he still loves Rihanna

Rihanna, who Glamour named its 2009 Woman of the Year,  said she's looking for opportunities to use her personal battle to help other women. "Domestic violence is a big secret," she says. "I want to give as much insight as I can to young women... to help speak for them."

Rihanna is set to talk about Brown again with Diane Sawyer in a new three-part interview airing Thursday and Friday on ABC. Her new album, Rated R, comes out Nov. 23.
