Jennifer certainly deserved a vacation, as the actress has two projects set for release until next year. 

In September, she'll star alongside Miles Teller, Josh Brolin, and Jeff Bridges, among others in Granite Mountain.

The based-on-a-true-story film tells of the 19 firefighters killed in the Yarnell Hill Fire in 2013. 

Jennifer will also appear in the action-adventure movie, Alita: Battle Angel, out next year.
