Rihanna recently admitted to MTV News that she's done a lot of growing up in the last year since the release of her Rated R album, even launching her own company.

"A lot has — I won't say changed, but a lot has evolved since then," she said. "A lot of growing up, a lot of responsibility in terms of taking control of my business and stuff like that."

She added, "It feels so good, because the closer you are to your business, the clearer you are about a lot of things. And that responsibility doesn't feel like a burden. It feels like the right thing to do, and we just launched my new company Rihanna Entertainment, and I'm being managed by Roc Nation alongside of that. So I feel really good. It feels great to be home."
