I have a girl!crush on Milla AND Black Widow. So the two of them combined is like "!!!!!!" I can't see Tony resisting that. Because I wouldn't let him. ;) It is comic canon that they were together! So... heeeeee...

I have loved Rose Byrne since I saw her in Attack of the Clones as Dorme. Since then, I just keep liking her more with everything I see her in. So I don't blame you for wanting to use her a lot! :D
