The actress stops by "The Ellen DeGeneres Show" on Tuesday where she opens up about experiencing her first earthquake in Los Angeles while pumping breast milk ... and reveals why she chose to name her newborn son Bear.
Check out the video above to see how the "Divergent" star handled the 4.4 quake and find out why she chose the unique name for her third child.
