Sexy Stars: Week of May 5, 2015

With Cannes Film Festival and network upfronts (TV advertising sales parties) underway, stars are putting their best foots forward on the red carpet.

Sienna Miller, who usually likes to stay covered up, wowed at Cannes in a flirty black dress with a deep plunge in the front. The actress, 33, who is a juror at the festival, paired her LBD with satin heels and wavy hair.

Model Doutzen Kroes, 30, also turned heads on the red carpet in a sleek white gown with a thigh-high slit and fluid cut-out.
