It's a whole new reason to nip out for a pint.

Inventors of this lager tipple in Bulgaria claim their Bohza beer has been brewed specifically to make boobs grow bigger.

The beer - brewed from fermented wheat flour and yeast - was originally developed as a health drink to help new mums having trouble breast feeding.

Now women are flocking to brewers Yavor-M in Ruse after drinkers started to record some eye-popping results.

Spokesman Kristian Gyoshev explained: "We make no special claims but we get hundreds of testimonials from women who say their boobs have gone up one or two cup sizes.

"It's natural, healthy, fun to drink and cheaper than any surgery."
