Watch Rihanna, George Clooney Play 'Never Have I Ever' on 'Ellen'

Guests attempt to expand meanings of "drunk before noon" and "hooking up"

Rihanna and George Clooney stopped by 'The Ellen DeGeneres Show' to play a dirty game of "Never Have I Ever"

Rihanna and George Clooney both appeared on The Ellen DeGeneres Show to play an especially dirty game of "Never Have I Ever." The host quizzed the pop star and actor on their texting habits and tried to define "hooking up" for Rihanna.

DeGeneres had previously played the game on her show with Madonna and Justin Bieber. This time, the more unlikely pairing of celebrities led to some uncomfortable truths from all three playing the game. With paddles in hand that said "I Have" and "I Have Never," DeGeneres launched the game with "Never have I ever texted a nude selfie." Rihanna slowly showed her "I Have" side of the paddle while Clooney and DeGeneres both raised "I Have Never."

The host got specific when she posed "Never have I ever swam naked in Lake Como," where Clooney famously lives. When Clooney was the only one to admit he has, DeGeneres tried to flip it into an invite to the home for her and Rihanna.

The guests tried to open up the meanings of all the topics, like when DeGeneres asked if they had ever been drunk before noon. Both Rihanna and Clooney were wondering if being drunk until 4 or 5 a.m. counted. All three also had differing opinions on what "spanking a cat" and "hooking up" — which ranges from just meeting up to "licking the envelope" for Rihanna — as the game progressed.
