I Just Found Out Everyone Calls Robert De Niro "Bob," So Here Are 15 Other Celebs Who Go By Names You'd Never Call Them

I just never clocked him as a "Bob."

Yesterday, my worldview slightly changed when I was reading an interview with Jennifer Lawrence, and she referred to Robert De Niro not as Robert but as his nickname, Bob.

Yes, Bob.

Jennifer told E! a story about her wedding and casually dropped the name Bob when talking about Robert: "I looked over, and I saw Bob, who doesn't know anybody, and he's kind of wandering around, and I immediately was like, 'No, this isn't what he wants to be doing. I don't want him here," she said. "So I went over and whispered, I was like, 'Go home,' and he was nice — he, like, talked to my parents and was polite — but I was like, 'Go.'"

I did a little search on X and found that Zac Efron also calls Robert "Bob."
