Keeley's bust is a Tea cup

British women have the world's biggest boobs because they drink tea, says Page 3 beauty Keeley Hazell, as reported in The Sun.

The 23-year-old revealed her theory after showing off her 32E cleavage in US mag Maxim.

Keeley was asked if all UK girls were so well endowed.

Londoner Keeley, now living in LA to pursue an acting career, said: "Sadly enough, I have actually Googled this. And British women have the largest breasts in the world, as told to The Sun.

"It has to be something in the tea we're always drinking."

But for all girls now reaching for the kettle, Keeley warned: "With great breasts comes horrible backache."

Recently Keeley was voted one of the world's top five most attractive women.
