On Trend: MTV Movie Awards

Long lashes, raspberry lips, and dimples to spare, McAdams shines at one of her first MTV events. To get similar golden highlights, try a heat-activated lightening spray, like John Frieda Sheer Blonde Go Blonder Controlled Lightening Spray ($13.84; amazon.com).

Arguably MTV's brainiest personality, Pak shows that she, too, can have some fun with flower accessories and flame-colored highlights.

Leave it to Jessica to try out reverse ombre hair! The very bronzed beauty was ahead of (or behind) her time with this adventurous dye job.

Hudson sticks to one of her summer staples as she pairs silver eye shadow with tangled ringlets. Her frosty makeup look reminds us that working with cool tones (like she does here) is always a skin tone-flattering idea, even during summer months.

Yes, even flyaways look dreamy when they're against Alba's sun-kissed skin. We like how she anchors her earthy look with elongated brows and a hint of lip gloss.

The chromatic-chameleon sticks to a mahogany hue and blunt bangs before trying out many asymmetrical looks in the years to follow.

Diaz balances her boho, mussed-up strands with precise eyeliner, sculpted blush, and bright coral lipstick.

We love how this Brit actress lets her freckles peek through her makeup. To do the same at home, trade out your foundation for tinted moisturizer and spot cover select areas of skin as desired.

Akerman suits up her slick 'do with drawn-on brows and kohl-rimmed eyes. Her glowing skin and nude lipstick add a modern edge to this Victor Victoria look.

Fox dons the "mullet" of red carpet hairstyles with this sleek-in-front and glam-curls-in-back coiff. We like how she mirrors the texture of her hair with a subtle sheen on her forehead and cheekbones.

The Twilight star rocks a 1960s coiff with decade-fitting bronze-free skin and a splash of red lipstick.

Before her new day job as co-host of The Voice, this sultry singer used her onstage time to try out funky bouffant hairstyles, like this one.

Bust-baring tops are one way to pull off Smurf-shaded hair. While we admire Perry's bold look (check out her double eyeliner!), we're most impressed with her electric pink pout.

Even somber starlets like to beat the heat (and frizz). To wear a look like this in real life, pull back wet or just-gelled hair and secure it in a ponytail. Then, use the tips of your fingers to loosen strands into slight ridges.
