For Madonna, age has always been just a number.
But in the latest issue of 'Rolling Stone' magazine, the 56-year-old pop star confessed she's often a victim of ageism in Hollywood — and frankly, she's sick of it.
"It's still the one area where you can totally discriminate against somebody and talk s**t. Because of their age. Only females, though. Not males. So in that respect we still live in a very sexist society," she told the publication.

"No one would dare to say a degrading remark about being black or dare to say a degrading remark on Instagram about someone being gay, my age — anybody and everybody would say something degrading to me. And I always think to myself, 'Why is that accepted?'" the mom-of-four continued.
Though Madonna says she definitely feels the pressure to act her age, she isn't ready to change who she is as a person just because she is growing older.

"[Everyone] judging me by my age. I don't understand. I'm trying to get my head around it. Because women, generally, when they reach a certain age, have accepted that they're not allowed to behave a certain way. But I don't follow the rules. I never did, and I'm not going to start," she added.
While the star — who is known for her over-the-top performances — admitted she loves being "provocative" while in the spotlight, her ex-husband, Guy Ritchie, wasn't always a fan of her antics.

"I think there probably was a time when I was less provocative. That's when I was married. Yeah. I don't think my ex-husband approved of it. Or, maybe he didn't understand it. I don't think he understood my provocation. He was not a fan of me kissing Britney Spears onstage, for instance. Was that provocative? I think it was," she told 'Rolling Stone.'
