Ronda Rousey: I'm a Sucker for a Good Tearjerker

UFC badass Ronda Rousey's secret is out ... she's a big softy at heart.

Check out the book Rousey was carrying Thursday as she left Glendale Fighting Club. It's Jojo Moyes' wildly popular romantic novel "Me Before You," which was made into a major chick flick that came out last week.

Yup ... sometimes fighters need a good cry too.
