"What's hooking up? That's such a broad term."

Rihanna, George Clooney and Ellen DeGeneres played a game of "Never Have I Ever" on Thursday's Ellen show.

DeGeneres asked a range of questions about nude selfies, being drunk before noon, dirty texts, spanking cats and hooking up.

Rihanna started out with the first "I have," when DeGeneres asked about texting someone a nude selfie. "Yeah, right, George," the singer said when Clooney held up an "I have never" paddle. "I do a lot of things on Instagram," he joked.

The trio talked about the definition of "hooking up" in regards to the question of "hooking up in the back of the car" and also debated whether being drunk before noon including being drunk at 6 a.m.  from the night before. Clooney admitted he has forgotten the name of the person he was "fooling around with" but with a smile added, "I want to say it was because I was drunk before noon."

In a different segment for the show, Clooney recounted his romantic proposal to his wife, Amal.
