Jennifer Lopez has revealed that her hair began going grey at the age of 23.
The popstar said that the stress of working in the film industry caused her hair to go grey.
She said on a US radio show: "My mum and my dad both went grey at a young age and I did too. At 23! Once I got started doing movies, I started to [go] grey."
Lopez added: "It was the stress, the pressure."
The 'American Idol' judge also said that she was "honoured" to be voted People magazine's most beautiful woman in the world this week.
She said: "I'm not 20 years old anymore, so I was very excited about it. When I was told about it, I was like, 'What?' But it's obviously very flattering. It's a great honour to be talked about in that way.
"Since I've been married, seven years this year, people don't really compliment me anymore. But girls do. I love girls and I love my girlfriends… I'm always very friendly towards women."
