Just five months ago she gave birth to her first son, Evangeline Lilly is back on the red carpet and looking better than ever! The Lost star hit the Los Angeles premiere of Real Steel looking white hot and wondrous in a slitty, Reem Acra gown that showed off her blockbuster booty to perfection.
Olivia Wilde slipped up with her style at Paris Fashion Week, sporting matronly a la mode to the Tod's Signature Party. The bigscreen baby wore a red embroidered gown that was better suited for Dame Helen Mirren.
And as for wacky, Lady Gaga hit the streets of NYC in a shredded dress, showing off her Smurf-colored hair in a bizarre updo.
