Simple Bae is JLaw's best friend, according to her; waiting for them to date, tbh.

What is something you learned about yourself that surprised you?
[Referencing Liam Hemsworth] I guess the thing that surprised me is that I would never expect to ever have a man this good-looking ever be my best friend. I just would never assume those things could happen, but he is. He’s the most wonderful, lovable, family-oriented, sweet, hilarious, amazing guy. He actually taught me how to be fair and to stand up for myself. It’s my biggest weakness: negotiating. I’m a wimp about standing up for myself and Liam is always fair. He’s always on time, he’s always doing his job, and he’s good about making sure that things stay fair. He’s teaching me to toughen up a little bit. That was important, I need that.
