Aubrey Plaza has a sex scene with De Niro in the new movie Dirty Grandpa and while it appears to have gone well overall, it seems she inadvertently upset him by doing something he really didn't like. Appearing on Jimmy Kimmel Live, the actress explains that her sex scene with Robert De Niro took pretty much an entire day of shooting. There was nothing specifically scripted to occur, so director Dan Mazer would give Plaza  number of different ideas about what to try to see and what worked well. At one point he suggested she started kissing Robert De Niro's nipples and De Niro didn't really like that.
"He was, like, batting me away. And I didn’t know if it was, like, in character or not, because you never know with him. They cut the camera, and then Dan called me back, and he’s like, ‘Bob does not like his nipple area paid attention to. So don’t do that!’"
So yeah, if you're ever working with Robert De Niro in a sex scene, do not suck on his nipples. You can check out a clip from the show below:
