Katy Perry Talks Rihanna, Dark Side of Music Industry

Katy Perry, 28-year-old singer and songwriter, has had a public friendship with singer Rihanna and recently spoke about her thoughts about the Barbadian pop star after rumors of a feud were sparked earlier this year.

Perry, who took the Billboard charts by storm with her hit song "I Kissed a Girl" in 2008, is the cover girl of September's Elle UK magazine where she spoke about the singer and a dark side in the music business.

"I love her [Rihanna] and every time I see her, I'm reminded of the light that she has," Perry told Elle U.K. "There's a lot of dark in this business...I know a lot of people out there with the most detrimental entourages - they are the root of their demise."

While she didn't name anyone specifically, Perry insisted that she was finished saving high profile public figures.

"It's really unfortunate but you can't save these people," Perry told Elle U.K. "My days of celebrity saving are over."

Earlier this year, Rihanna, 25, and Perry were the subject of reports that the latter disapproved of a reconciliation with ex-boyfriend Chris Brown who physically abused her in 2009.

"They're barely talking and ever since the couple reunited, there has been tension between them..." a source previously told The New York Daily News' Confidential. "Katy fears Rihanna is making a huge mistake and doesn't want to be part of it."

Rihanna previously laughed off rumors that she and Perry were at odds over the former giving her friend relationship advice.

"Katy Perry can date anyone she wants," Rihanna said in a Now Daily report last May. "Besides, who the (expletive) am I to say anything? I could never give relationship advice to anybody!"

An Us Weekly source reported that Rihanna and Perry reunited with one another last May after some time spent apart.

"They hung out like old times and were catching up," the source told Us Weekly last May.
