Amber Rose says the key to happiness is not to worry what anyone else thinks of you.

The singer has been hitting headlines this week thanks to a massive Twitter row between her ex-husband Wiz Khalifa and rapper Kanye West.

But now Amber has penned an op ed for Time magazine, insisting she is much more content in life now that she doesn't take any notice of anybody's opinions of her.

She wrote: "After my ex-husband Wiz Khalifa and I got a divorce, I'd go out for a date at a restaurant like any normal single human and people would say, 'Man, she's such a ho. She's out at restaurants with guys.' Then they would see my ex-husband with a bunch of women. They would say, 'He's the man! That's so cool.' So when I went on a date, I'm a whore, and when he's piling girls in a car, he's the man? There's something wrong here.

"It wasn't just men saying these types of things. There were a lot of women saying hateful things to me. I was getting torn down constantly. But in the past year, I've just started not caring."

Amber, who has a two-year-old son Sebastian with Wiz, added she now "sleeps like a baby at night" after having the realisation.

She continued: "What I've realised is that, when you care too much, you're not living at your full potential. When you really stop caring about what people say, that's when you really start living. It's such an amazing feeling. It's about loving who you are, owning who you are and knowing that it's O.K. to live your life how you want to live it. We're all human, which means we're not all perfect. It's so cool to think that I might help women think about who they want to be and then encourage them to be that person with no remorse. I want to help women just be happy in their own skin."
