Why doesn't Jennifer Lawrence star in a Comedy?

I think Jennifer Lawrence is an outstanding actor, I just feel like most of the time she's cast in so many dramas or heavy movies. I think Jennifer and her management team should take a chance and see about getting her cast in a comedy. It really feels like waste of her bubbly personality and comedic skills not to have her star in more comedies, romantic comedies or just anything more fun and lighthearted.

What do you think should she star in more comedies/romantic comedies?
