Pop superstar Rihanna explains why she began using social networking site Twitter.com in the July issue of Cosmopolitan, which hits newsstands Tuesday, June 7.

"I was so against Twitter. I couldn't understand how people were supposed to care what I was doing at any given moment," she says.

"Then I started to figure out you can treat it like a giant chat room: I can respond directly to people's questions. It makes it easier to deal with the flak around you because now people have a sense of who you are."

The singer, whose new single "Man Down" is causing a bit of a stir, also opens up about the aftermath of the domestic violence incident she went through with ex-boyfriend Chris Brown.

There was definitely something subliminal happening," she tells Cosmo. "I walked around with a very f**k-you attitude."

And speaking of Twitter and Brown, recent rumors have started swirling that the couple are secretly getting back together. According to Monsters & Critics.com, a source tells Now magazine, "She's trying to find a way to take him back publicly without letting down her supporters, her management and herfriends, or setting a bad example."

Rihanna was recently scolded by her fans for following Brown on Twitter.
