It was all glitz and glamour at the 80th Academy Awards, but who stole the spotlight with the most jaw-dropping style? "Extra" picks Heidi Klum's elegant 'do for Best Hair, and her beautiful bun set off more than flashbulbs. "I set off the beeper when I went through security!" she admitted. "That's my 120 pins!"

Smokey-eyed "Juno" star Jennifer Garner also ruled the red carpet in a luscious black Oscar de la Renta frock, made even more glamorous by 136 carats of eye-popping ice from Van Cleef & Arpels.

For the boys, bowties were back big-time, and "Extra’s" Best Dressed Man award goes to Giorgio Armani-clad George Clooney … who had little competition.

For Best Dressed Woman, it’s radiant-in-red bombshell Katherine Heigl, whose off the shoulder, screaming red Escada gown practically knocked people over!
