With cameras flashing around them at all times, celebs best be ready for a photo op at any moment.

Lady Gaga is known for her eccentric fashion sense, but the pop star-turned-jazz crooner toned it down in a relatively pedestrian outfit. The "Mother Monster," 28, channeled Marilyn Monroe in a slinky sheer white gown and platinum blonde hair.

Actress Sienna Miller, 32, also channeled old Hollywood glam in a very sexy white cocktail dress. The stunning sheer frock featured a retro Bardot neckline and beaded tassels.

Fashionista Kate Bosworth kept it casual in her usual tailored-boho look. The actress, 31, looked put-together in on-trend cropped-flared pants, printed sweater and black brogues.
