Katy Perry and Rihanna used to be inseparable, but in recent months it's been obvious that their friendship fell off. The "Firework" singer addressed the situation during a recent interview with Elle UK, revealing that she still "loves" Rihanna, but admits that she has a "detrimental" entourage.

"I love her [Rihanna] and every time I see her, I'm reminded of the light that she has," she told the magazine. "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."

She added, "It's really unfortunate but you can't save these people. My days of celebrity saving are over."
