What woman would you think I should use for my story?

I will make this short so you do not have to read a lot of explanation. The important point of my new story is that a scientist does not believe in art or religion. He only believes in science. He is on his break and he meets suddenly a woman who approaches him. He thinks she is very attractive. She introduces herself and shakes his hand. However, she will not let go. She tells him she is from another planet and her human form is merely a hologram. He does not believe her and he thinks someone at his work spiked his coffee with acid. What woman would you pick to represent her? I appreciate your opinions.
