Pharrell Williams named his album 'G I R L' because women have been ''loyal'' to him throughout his life.

The 'Happy' hitmaker believes females could ''cripple'' the human race if they all united and he wanted to create an LP that would honour empowered ladies everywhere.

He explained: ''I instantly knew that the name of the album was called 'G I R L', and the reason why is because women and girls, for the most part, have just been so loyal to me and supported me.

''There is no breathing human being on this planet that did not benefit by a woman saying yes twice. Yes to make you, and yes to have you. Point-blank.''

The 40-year-old musician further emphasised his homage to women on the album, revealing that gender is one of the main themes across his new songs.

He said: ''If women wanted to cripple the economy, all they gotta do is not go to work ... if they wanted to end our species, cripple our species - seriously! Like, women can look out into space at all the stars and go, 'You know what? I can actually end all the human life on this planet right now. All I gotta do is just say no.'

''There's a huge value placed on that - on something so simple like if all our talk-show hosts late at night all were women, that's a very different world.''
