World’s sexiest volleyball star Kayla Simmons shows off major underboob in bikini as she leaves little to imagination

KAYLA SIMMONS proved she doesn't need push-ups to keep in shape as the world's sexiest volleyball star posed in a bottom-heavy bikini top.

Fans called the social media sensation the "prettiest girl ever" and "My Queen" while one asked "Marry me?" as she shared snaps from Europe.

The Californian, 27, turned Italy extra-romantic for her followers with a succession of idyllic images on her extended trip.

Kayla herself posted: "That Italian sun."

And one observant fan posted: "Beautiful setting, gorgeous woman!! The sun hitting you in all the right places!"

But some followers from across the pond are hoping she soon shares her attributes in her home country. 

One wrote: "You should try Colorado".

Multi-lingual praise included "Bellissima"; as the sunny pics persuaded followers to turn on the charm.

Before Ityaly Kayla was earlier in Switzerland and France, where she was unfortunately hit by bird poop.

But it was her fans who were more eagle-eyed - in spotting her array of minimal costumes. 

And she seemed most impressed with the Italian Riviera - judging by one message.

Posing in a pink bra in Cinque Terra, she labelled the historic seaside escape her "dream village".
