Since I don't know any current celebrities by name, I couldn't answer the question. If she asked me about old-timers, I might be able to answer. I don't think it's wrong to ask the question.
@WendyLopez43 Just tell him it's OK you're not the jealous sort then I guess. so many problems could be solved if people actually talked to each other and I mean they do but they don't REALLY talk about it the way they should and about the things that matter.
When a wife asks her husband that question yes, it does cause serious mind freeze!
Because he fears the, "Oh, don't you wish I looked like her?", "Oh, so you would cheat on me with her would you?", "Oh, you want to do her?", "Oh, you think she is hotter than me?", and so on and so forth if the poor guy answered your question honestly!
Let me explain. You are playing innocent, but all men know. If you are dating a woman and she asks this. It is a test and a trap. He knew there was no good answer. He knew no matter how he answered, he would suffer. Unless he said, "Honey, you're enough."
He probably figured you were trying to entrap him. Even if you weren't, it's something a lot of women do. He's seen it happen other guys, regardless of whether it's happened to him.
