SF-RomCom hybrid

On another message board we're talking about mixing genres, and one
that's come up is blending Science Fiction with Romantic Comedy.
Basically When Harry Met Sally with Star Wars or something.  I think
Earth Girls Are Easy and Heartbeeps are probably contenders for that
mix, but it's been so long since I've seen them that I can't say for
sure.

Can anyone else think of some SF-RomCom hybrids?
