You know that friend of yours who always asks you about a thousand probing questions about the meals you eat? (I once had a vegan friend who used to take me out to fancy restaurants and request that I describe in painstaking detail the delicious meaty dishes I was eating. Wait -- is that weird?

To hear Neve Campbell tell it, Dwayne “The Rock” Johnson is like that, too.

Campbell recently paid a visit to The Late Show with Stephen Colbert, and revealed that Johnson, with whom she is co-starring in the movie “Skyscraper,” has an interest in other people’s meals that’s as big as his bicep.

“He does this weird thing… Every time you go have a meal, you go and see him and he says, 'What did you have?' You say, 'I had a salad.' 'What did you have in your salad?' 'Feta cheese.' 'What else?' ‘Tomatoes.' 'What else?' 'Salmon.' 'How'd you have the salmon?'” she said. “It's like the weirdest thing. He's obsessed with other people's food. It's like porn for him.”

What gives? Campbell’s explanation is that Johnson’s (like my friend’s) interest comes from a place of privation.

“Because every four hours -- or maybe it's every two hours -- someone walks up with a little tin … with, like, pieces of meat in it or whatever he’s allowed to eat in that two-hour period. It's like a machine, right?” she told Colbert. “So, he's just jealous. All he wants to know is what people eat.”

Awwww. Never thought you’d feel so sorry for a guy whose nickname was “The Rock,” did you?
