Depends how easy your friend would handle that information. Also they might not like you to watch porn movies. If she objects that she might even more object that other info. You could end in a sad way in some alley.

Do you want to put land between yourself and your friend?

Depends on her humour. If you joke about pornos already then you might get away with a cheeky remark linking them to the porno actress, but otherwise think of how they'd think of you knowing that you thought of them because of a porn actress...

It depends on her personality and what kind of stuff you two can talk about or joke about. If she's the kind of person who would say "Ew, too much information" in regards to porn then no. I wouldn't mind and I think that other people shouldn't mind but some people might not want to hear stuff like that or all the details meaning what kind of movie it was.

It might be off-putting or seem creepy to your friend.
