I really can't see it, she is a very attractive and trendy girl.
If the photos of him are how he looks now, I can't imagine her wanting to have sex with him just like that, randomly pick him up in a bar and head off for sex. Drunk or not.
If he was really hot, I might have a different perspective, or if she knew him already, and knew him as a person, than I would also think differently.
Very shallow perspective on the looks front, I realise.
Maybe she did know him previously, that has not been commented on yet, that could throw a whole different light on the matter, but as it stands now, no, I very much doubt she chose him as the one she wanted to have sex with that night.
