"As gay marriage remains a topic of heated debate, we take a look at the 10 most inspirational quotes from celebrities around the world."

Stephen Fry



"At least 260 species of animal have been noted exhibiting homosexual behaviour but only one species of animal ever, so far as we know, has exhibited homophobic behaviour â€“ and that's the human being."

Lady Gaga



"I feel the denial of gay marriage sends a prejudice message. Our youth deserve a fair and hopeful future with government that values us equally."

David Cameron



"Conservatives believe in the ties that bind us. Society is stronger when we make vows to each other and we support each other. I don't support gay marriage in spite of being a conservative. I support gay marriage because I am a conservative."

Will Smith



"If anybody can find someone to love them and to help them through this difficult thing that we call life, I support that in any shape or form."

Brad Pitt



"Equality, absolutely, that's what defines us. It's what makes us great. If it does not sit well with your religion, let your God sort it out in the end, but that is us. We are equal."

Mariah Carey



"If two people want to get married, it is their prerogative — we hope. Everybody should be able to do what they want to do and be in the pursuit of happiness."

Jay-Z



"What people do in their own homes is their business, and you can choose to love whoever you love. That's their business. It is no different than discriminating against blacks. It is discrimination, plain and simple,” said the Hip Hop mogul in response to President Barack Obama's stance on marriage equality."

Ellen DeGeneres



"Portia and I have been married for 4 years and they have been the happiest of my life. And in those 4 years, I don't think we hurt anyone else's marriage. I asked all of my neighbours and they say they're fine."

George Clooney



"At some point in our lifetime, gay marriage won't be an issue, and everyone who stood against this civil right will look as outdated as George Wallace standing on the school steps keeping James Hood from entering the University of Alabama because he was black."

Ricky Martin



"Unfortunately, we don't have the option of marriage in our country. We could go to Britain or Spain or Argentina and do something symbolic, but that's not what I want. I want to have the rights of anybody else in my home country. I don't want to be a second-class citizen.";
