Strapless cocktail dresses in bright colors and middle-parted hair ruled the red carpet at Spike TV's Guys Choice Awards on Saturday, June 7, in Los Angeles. Read on to see the sexy looks worn by Jessica Alba, Sandra Bullock, Olivia Munn and more!

Jessica Alba amped up the sex appeal in a strapless David Koma dress with a leather caged bodice and sheer panels. The presenter styled her hair in a middle part with bed-head texture and added a sultry smoky eye and nude-pink lip.

Jaime King, with sleek blonde hair and dramatic black eyeliner, wore an edgy Emilio Pucci mini with a crystal-embellished plunging neckline and carried an equally sparkly Edie Parker clutch.

Chrissy Teigen, who was honored with the Holy Grail of Hotness award, opted for a bright yellow strapless Three Floor dress with a sweetheart neckline, paired with nude gladiator sandals by Casadei. The supermodel's long brown hair was styled in messy waves, and she wore a coral lip color.

Camila Alves wore a simple black strapless dress with silver metallic heels while the Decade of Hotness honoree, Sandra Bullock, played the part in a hot pink Roland Mouret dress with ankle-strap heels.

Olivia Munn wore a deep green J. Mendel dress that featured a draped silk bodice and a faux-wrapped leather skirt.
