Happy birthday to Bruno Mars! Today, Oct. 8, 2012, the 'Locked Out of Heaven' crooner turns 27 -- in honor of Mars and his super fly status, we're paying tribute to him with a readers poll of his best hats, from his many signature fedoras to baseball caps and beanies.

There is no doubt that this Hawaiian loves his head adornments. Chances are, more than half of the time you see him, Bruno Mars will be rocking some sort of hat -- and it's not even for any other reason besides the fact that he's a total bada--, since he's got one luscious head full of hair too.

In the first picture above, you can see him chilling out with his pet dog Geronimo wearing an off-white, creamy-colored fedora. Next up, Bruno stopped by 'The Mark Hoppus Show' a few years back wearing a red beanie cap, which is another one of his favorite head toppers, especially during the colder months. Then there's the awesome chocolate-y, brown fedora Mr. Mars rocked at a red carpet event, which looks extra cool thanks to the yellow feather.

But fedoras and beanies aren't the only hats the pianist/singer/guitarist/songwriter wears upon his lovely dome. This mans man also loves his fitted baseball caps, like the Los Angeles Dodgers hat he's wearing in the black and white photo above, and old-school snapbacks as well. Finally, we're back to fedora territory with the last photo, with Bruno wearing one of his favorite gray chapeaus during a performance.

So, out of the five hats seen above (which are far from all of the hats Bruno has in his wardrobe), which is your favorite? Vote on the Bruno's best hat below and send him some birthday love in the comment section.
