Despite a struggle earlier in the game, when the Transformers star failed to remember what a frog looked like, Fox and her Pictionary partner Nick Cannon earned their ultimate winners title by beating Fallon and teammate Wiz Khalifa to the final answer.
Competitive Fallon, who had struck lucky earlier in the game when Khalifa had correctly guessed what his drawing of a puppeteer was, put his head in his hands as Cannon shouted out the correct answer to his partner Fox.
Mom-of-two Fox, who looked slim in a tight-fitting gray dress with orange detailing, revealed to Us Weekly earlier this week that her youngest son, Bodhi, is growing up big and strong.
"Bodhi is finally starting to talk a little bit," the actress, 28, told Us exclusively. "He is nearing 6 months. We did just take him to the doctor, and he's an enormous child. He's in the 95 percentile for height and weight. I've got a beast on my hands!"
