A new week just means more red carpets, events, parties and galas for Hollywood's sexiest stars.
This week, Alessandra Ambrosio, 33, stood out in an extremely daring gown that only a supermodel could get away with. The Victoria's Secret Angel is used to baring (almost) all on the catwalk, but this time, she flaunted her hot bod on the red carpet.
Emma Roberts opted for a more conservative, yet totally adorable, look for a separate event. The "American Horror Story" actress, 23, channeled the '60s in a hot pink number with a fun collar. Mary Janes and her pixie cut completed her retro look.
Reese Witherspoon, 38, was spotted pumping gas in a casual chic outfit that consisted of a cheeky leopard-print skirt and pointy stilettos. A messy bun and oversized scarf kept the look daytime-friendly.
See the rest of our picks for this week's sexy celeb style.
