HOLLYWOOD: Hollywood star Demi Moore is tired of being hailed as the "poster girl" for age gap relationships because of her successful marriage to actor Ashton Kutcher who is 16 years younger than her.

The 47-year-old actress is not quite happy with the fact that people look up to her as an example of how a romance between an older woman and younger guy can work, reported W magazine.

"I'm certainly not the first person to be in a relationship with a younger man, but somehow I was plucked out as a bit of a poster girl.

"I don't know why that is. But I just kind of step back sometimes and say, 'There is some reason, and what is it that I have to share in a positive way?'," said Moore.

The 'Ghost' star is not keen on being referred to a cougar, the slang term for a sexy older woman who dates younger guys.

"I prefer to be called a puma," said Moore, who has been married to Kutcher for four years now.
