• Jennifer Lopez plays the mother of NCAA wrestler Anthony Robles in 'Unstoppable.'
• Jennifer Lopez said she asked herself if she was enough for her kids when she was a single mom.
• She shares two kids from her previous marriage with Marc Anthony, which ended in 2014.

Jennifer Lopez said she wondered if she was enough for her kids.

In an interview with Entertainment Weekly published on Monday, the actor opened up about being a single mom.

"I've been a single mom at times in my life and [I've asked], 'Am I enough for them?'" said Lopez. "And the truth is, all you need is really one good parent to love you."

Lopez, 55, is the mother of 16-year-old twins Emme and Max, whom she shares with her ex-husband, Marc Anthony. The couple married in 2004 and divorced in 2014.

In the film "Unstoppable," Lopez plays Judy Robles, the mother of NCAA wrestler Anthony Robles.

The film, scheduled to stream on Prime Video on January 16, is based on the true story of Robles, who was born with one leg and went on to become a champion wrestler in college.

"You hear it in Anthony's voice, and look what he's been able to accomplish," Lopez continued. "That's what the movie gave me: You are enough."

In May, Lopez discussed raising teenagers on Live with Kelly and Mark. "I'm alone in this in the teenage years," she said, explaining that most of her close friends don't have kids. "So yeah, it's challenging, you know, but I love my kids, and they are so brilliant and lovely and beautiful, and I enjoy it."

Lopez, who is in the middle of a divorce from Ben Affleck, is not the only celebrity to have had questions about parenthood. In October, Hoda Kotb, who adopted two daughters, said she wondered whether she deserved her kids at one point.

"And I thought, 'I'll just work really hard to be really good, because I'm not sure,'" she said.

In April, Ashley Espinoza, who has a daughter, wrote for BI about the loneliness of being a single parent.

"I focus my attention on something I can control, like paying off my student loans, writing a book, and having fun with my daughter every chance I get, assuring her that one parent can be enough," she wrote.

Sheila Hageman, a divorced parent with three kids, wrote last year that she's learned to cut herself some slack.

"I'm giving myself the grace to recognize that the experts aren't living our lives and that I don't have to be a 'perfect' single mom but rather a good-enough mom who loves her family and is willing to be flexible and creative in the face of challenges," she wrote.

A representative for Jennifer Lopez did not immediately respond to a request for comment from BI sent outside regular business hours.
