So the OP wanted a list of celebrities you pretend you don't think are hot around your partner.
I think the more fascinating thread, after reading the Jenna von Oy comment, is celebrities you had a crush on, who aren't exactly in the limelight of OMG SFH territory.
Like on Lost, while Kate was all-time Mount Rushmore, who wants to get in line behind Jack, Sawyer, Nathan Fillion, and that idiot doctor she got killed? On my rewatch a couple of years ago, Sun was my top pick, although that carries the inherent risk of Jin snapping my neck in the middle of the night.

Or in Cap: Civil War, I'd take Emily van Camp over Scar Jo or Elizabeth Olsen.
