Jennifer Lopez reflects on life as a single mom to her 16-year-old twins, Emme and Max, on the latest cover of ‘Entertainment Weekly.’ The 55-year-old opens up about the challenges of parenting, admitting her biggest question is, ‘am I enough for my kids?’ Jen’s cover comes as she takes on the role of Anthony Robles’ mother in ‘Unstoppable,’ a biopic about the NCAA champion wrestler born with one leg. The film, produced by her ex Ben Affleck, streams on Prime Video starting Jan. 16.
