At the Emmy Awards in L.A. in September 2011, Paltrow, 39, turned heads in a sexy, see-through Emilio Pucci ensemble. The black and nude look exposed the actress' toned tummy -- and made fellow nominees envious.
"I can't stand next to her too long. She looks too good," Parks and Recreation's Amy Poehler joked during an E! News interview. Paltrow later said she "tried on two dresses" before deciding on risque outfit.
Kardashian, 31, wore the same Emilio Pucci number during the Cannes Film Festival on May 22. Unlike Paltrow, the E! reality star showed less stomach and opted for more dramatic jewelry.
