Jennifer Lopez celebrates 'power of motherhood' in Ben Affleck's 'Unstoppable'

Jennifer Lopez is offering an inside glimpse into motherhood, revealing why women hide struggles from their children during a London screening event.

The 55-year-old American actress, who recently attended the London premiere of Ben Affleck’s upcoming film Unstoppable at Cineworld Leicester Square, opened up about playing the ‘smaller character’ in the film.

Speaking of ‘challenges,’ JLo revealed that the film is ‘very relatable’ for women going through tumultuous relationships.

The Boy Next Door alum reflected on portraying Judy Robles, who embraced motherhood when she was merely 16 years old.

Jennifer expressed pride in playing Judy, the mother of wrestling champion Anthony Robles, who overcame the odds of being born with one leg to become a champion and author, crediting his mother's 'unstoppable' spirit for his success.

She said of her highly-anticipated role, “I think a lot of women have gone through that, and she (Judy) and I talked a lot.

“We got to know each other. I wanted her to really feel safe with me (while) sharing details, because as great as the story is, without the struggle, that’s what makes it great.”

The mother-of-two further lifted the lid on hiding stuff from children as she went on to explain, “There was a whole different story there that she was living, that you hide from your children, you protect your children from that.

“But I thought it was really, really important to not just play the mom who the kids knew, but to play the woman who raised these children.”

Being a mother herself, the multi-hyphenate star described it as a beautiful experience.
