Will.i.am claims women with "double D breasts" and a "big old a**" will never be taken seriously.

The Black Eyed Peas rapper - who penned hit song "My Humps" in which bandmate Fergie sings about her "lovely lady lumps" - insists men can't see past a woman's body to bother to find out if she has brains.

Will.i.am told Radar magazine, "I always wondered what it must be like to be a girl, always getting pulled on. Maybe she is the smartest genius on the planet, but she is racking double Ds with a 26-inch waist and a big old a** and no one is ever going to see her like that because that's the way the world is today."

"When I wrote 'My Humps' I said, 'This is the stupidest thing ever,' but in a good way."

The hip-hop star - real name William Adams - recently revealed he composes tunes on the toilet.

The rapper has turned his home into a recording studio by installing recording equipment in every room of his $7 million Hollywood mansion.

Will.i.am said, "It's not really a house, it's a studio. There are microphones and places I can plug in everywhere, a wireless controller, so I record from anywhere."

"And I can log on from anywhere in the world, so even if I'm in London or Tokyo, I can still be making music."
