Is Kate Hudson a better liar than Jimmy Fallon? It would appear so. On last night’s episode of The Tonight Show Starring Jimmy Fallon, Hudson competed in a hilarious game of “Box of Lies” against the host—and she proved her prowess.

The actress, who looked sexy and svelte in a ’70s-inspired black-and-white Roland Mouret jumpsuit, was on the show to promote her new film, Wish I Was Here. After discussing her famous family and two sons with Fallon, the pair got down to business. During the “Box of Lies” segment, the actress charmed her opponent while playing the good-natured game. The rules were simple: Each competitor would select a box from the shelf and describe its contents to the other person. Hudson and Fallon then had to decide whether they were being told the truth or fed a lie in order to win the round. Hudson giggled her way through the competition and managed to fool Fallon with her acting skills while never actually lying about the contents of her boxes.
