So you're taking celebrities, mashing them together, and making a lesbian couple? What the fuck is that about? All of the ones you mentioned are implausible hypothetics - none of the damn women are even lesbians.
Argh! Some threads just annoy the shit out of me. You don't get to make your own lesbian couple and you damn sure can't choose straight women. It's not a paint by number. What's the point? If you're going to do this, choose actual, certified lesbians!
