When asked by the Bravo host if she "ever swam in the lady pond," The Other Woman actress, who was joined by her costar Leslie Mann, responded: “Interesting! What is the lady pond?” She then followed with, “Yes, I have been with a lady. Yeah."
Later, during a game of "Plead the Fifth," Cohen asked if it had happened more than once, to which Diaz, 41, replied, “You didn’t ask explicitly how I was with a lady, but I have been with a lady.”
This wasn't the first time Diaz opened up about women. The Sweetest Thing actress openly revealed in Glamour UK's May issue: "I think women are beautiful - absolutely beautiful … And I think that all women have been sexually attracted to another woman at some point. It's natural to have a connectivity and an appreciation for the beauty of other women."
The blonde, who donned a Giulietta jumpsuit for the appearance, was also questioned about dating a baseball player and told to name one movie she regrets starring in.
