The seven-year-old twins looked adorable in their red-carpet outfits, reported Us magazine.
Emme wore a beautiful pink princess dress with a pair of gold ballerina flats, her hair up in a pretty tight bun. Max looked dapper in a powder blue suit as he accompanied his mother to the high profile event.
But while Lopez and Emme seemed to enjoy their time in front of the cameras, the flashes appeared to get too much for little Max, who shut his eyes tight and grimaced as the photographers took their snaps.
Lopez's ex, Casper Smart also walked the purple carpet, as choreographer and creative director for the movie.
