Rihanna has revealed why she loves Katy Perry so much - because the Firework singer has "no edit button".
The stars are firm friends, with Rihanna even helping to organise Katy's raucous Las Vegas hen party ahead of her marriage to Russell Brand.
"All my friends are guys, to be completely honest. But when I met (Katy), it was such a breath of fresh air. I just couldn't believe this chick had no edit button," the What's My Name singer told US Glamour.
"Katy and Lady Gaga came out of the gate exactly the way they think, the way they want to dress, the way they want to speak."
Rihanna, 23, added: "There's a pack. It's me, Gaga, Katy Perry, Beyonce... 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."
But despite her positivity, the Barbados-born singer found it difficult to show the real her in the early days of her 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," she said.
"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 any more 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."
