MTV Movie Awards' Hottest Red Carpet Looks

By Jocelyn Vena

The MTV Movie Awards are the perfect place for celebrities to let loose and show off their fun, flirty and hip sense of fashion. Gone are the gowns and stuffy attire reserved for shows like the Oscars and the Golden Globes. In are the miniskirts and relaxed suits that best emphasize the chilled-out, party atmosphere of every MTV occasion.

We can't wait to see what our guests are going to wear at the show this Sunday night, but in the meantime, here are five of the best looks worn on the carpet in the last two years.

Megan Fox
In 2008, the "Transformers" star didn't need any jewels for her outfit. Instead, she rocked the carpet with rhinestone-encrusted straps on her white minidress, paired with her long straight hair and modernized bombshell makeup.

Zac Efron
Forgoing the casual look, in 2007 Efron opted for a slim-fitting gray suit and skinny gray satin tie, a retro fashion befitting the star of "Hairspray." Efron proved that guys don't need to be messy to embody the fun, carefree feeling of the Movie Awards.

Lauren Conrad
In 2008, wearing a slinky, knee-length, one-shouldered blue dress, LC embraced her "Laguna Beach" roots by keep her hair in loose, beachy waves and accessorizing with two simple gold necklaces.

Robert Pattinson
With his now-infamous devil-may-care hair in place, the "Twilight" heartthrob greeted the screaming fans on the 2008 red carpet in a gray, sharkskin blazer, slightly unbuttoned black shirt and black jeans. The look showed everyone that RPattz is one of the hottest young guys in Hollywood.

Cameron Diaz
The little black dress never fails, and Cameron's funky, polka-dotted take on the idea was adorable in 2007. Plus, the very short length of it was perfect for Cameron's super-long legs. Her relaxed hair and makeup kept the style light, airy and fun.
