Katharine McPhee's Smashing In Elie Saab

Does anyone have a thermometer? Because we have a Phee-ver!
Katharine McPhee looked like a headlining star at the Met Gala last night.
The Smash actress showed off her bod in an orange beaded Elie Saab gown that would make Marilyn Monroe jealous!
Katharine’s come a long way since her American Idol days, no?
