Rihanna fires up the September 2011 cover of Glamour and the magazine has released some of the singer's choice quotes from the feature, which celebrates RiRi's ever-evolving style, her bestie Katy Perry and how she hates perfection. We have to agree with the 'Man Down' singer; it's our flaws and our scars that make us interesting. Besides, perfect is boring, isn't it? Perfection? RiRi ain't having any of that.

RiRi also talks about fellow diva Lady Gaga, and how she used to shun pink or red lipstick. Why the "no" to a pink or red pucker? Read on to find out!

Besides dishing about her style and her sisters in the pop music sphere, she also addresses the "extras" that come with being a pop star, such as being as the pressure of being role model and setting an example while the whole world is watching.

The accompanying images of the singer channel classic, '50s-era 'Mad Men' glam, with RiRi wearing A-line sheaths and a crimson kisser.

On her BFF, Katy Perry: "All my friends are guys, to be completely honest. But when I met her, it was such a breath of fresh air. I just couldn't believe this chick had no edit button ... Katy and Lady Gaga came out of the gate exactly the way they think, the way they wanna dress, the way they wanna speak."

On fellow female pop stars: "There's a pack. It's me, Gaga, Katy Perry, Beyoncé…who else? Kesha, for sure. Women are definitely dominating music right now, and that's because we are competitive beings. I feel like music hasn't been this exciting in a while."

On her unique sense of style: "Getting dressed, I want to pick the most bizarre pair of shorts so I can figure out how to make it look right, or work an outfit that will make people go, "What the hell is she wearing?"

On hating drama ... And perfection: "I hate drama. But at the same time, nothing bothers me more than when life's perfect. And that's the sick part. I just love a challenge, whether it's a relationship, my career, clothing…"

On honesty: "I think honesty is the ultimate liberation in life. People want to shy away from the truth and keep sweeping it under the rug. But after a while, you pick up the rug and there's just way too much dirt, so you might as well just be upfront about it."

On setting an example: "I want to set the right example and, at the same time, live my life ... I feel like pop stars can't be rock stars anymore because they have to be role models, and it takes the fun out of it for us, because we just want to have fun with art."

On being a role model: "In the beginning of my career, it was really strict for me. I couldn't wear pink or red lipstick; it was just bizarre. We had a young fan base, and they were trying to keep me fresh. But I just really wanted to be myself. I wanted to be sassy, the attitude, all these things that I am."
