Kristen Stewart, Lindsay Lohan, Katy Perry Light Up MTV Movie Awards Red Carpet

Stars sport summer whites, bold blues and plenty of shine.

Hollywood's hottest stars shined brightly — quite literally — on the 2010 MTV Movie Awards red carpet, as sparkle and bling dominated the evening's sartorial choices along with white-hot and bold blue shades.

"Jersey Shore" star and red-carpet correspondent Nicole "Snooki" Polizzi flaunted her curves in a white Dolce & Gabbana minidress with a diamond mosaic design, while co-star Sammi "Sweetheart" Giancola rocked a black-and-white bandage-style dress. "Beastly" star Vanessa Hudgens was also white-hot in a frilly, empire-waist, white Jenny Packham frock with silver-jeweled detailing, as Paris Hilton showed off her gams in a cream-colored feathered mini by Blumarine. And the girls weren't the only ones working their summer whites, as "Jersey Shore" star Vinny Guadagnino walked the carpet in a white suit jacket paired with a white T-shirt and jeans.

Blue was the other standout color of the night, though, sometimes it manifested itself in unexpected ways. "California Gurls" singer Katy Perry showed up in a bright blue wig, which seems to be her new go-to awards show 'do, as she sported a similar wig at the Kids' Choice Awards in March. Although Perry joked she'd be naked during Sunday's (June 6) performance, she actually showed up nude, well, wearing nude in a long-sleeve sheer number with strategically placed rhinestones. [movie id="420622"]"Eclipse"[/movie] and "The Last Airbender" star Jackson Rathbone was also singing "the blues" in a teal satin jacket, while the lovely Eva Mendes looked stunning in a turquoise-and-silver Stella McCartney one-shoulder dress.

Lindsay Lohan bared plenty of cleavage in a sparkling silver Pamella Roland jumpsuit, as did "Eclipse" star Elizabeth Reaser, clad in a slightly more demure black tuxedo-style jumpsuit. Couture was the word for songstress [artist id="509026"]Christina Aguilera[/artist] who donned a black Versace gown with plenty of interesting details, including chains and peacock-esque feathers cascading from the back. And did we mention Christina's Rihanna-inspired updo? Kristen Stewart was also a designer darling in a D&G dress with a sparkling gold top and silver skirt bottom.

"Up in the Air" nominee Anna Kendrick was arguably one of the most colorful dressers of the night in a flirty, floral-print red Zac Posen dress. "The City" star Whitney Port also opted for color: a cheery yellow-and-gray minidress that played well off her blond hair.

For the men, the standard uniform seemed to be a suit jacket and jeans. [movieperson id="438080"]Zac Efron[/movieperson] sported a gray jacket with a baby-blue button-down (strategically unbuttoned at the top, of course). Taylor Lautner donned his signature leather jacket look, while Paul "DJ Pauly D" Del Vecchio rocked a black jacket and white tee. "Scott Pilgrim vs. the World" star Michael Cera eschewed this dress code, opting for a multicolored polo shirt that made him look a bit like a fast-food employee.
