Jennifer Lopez gets honest about motherhood: 'I almost thought that it wasn't going to happen'

Last week, Jennifer Lopez celebrated a double delight in her life. Her twins, Emme and Maximilian, turned 9 years old.

To mark the occasion, she shared a heartfelt message on social media in which she thanked God for letting her be their mother, and during a Thursday morning visit to TODAY, she explained just how deep that gratitude runs.

"They just made my life so much better," she said as her eyes welled up with emotion. "I'm forever grateful that ... you know, I didn't have kids until later and so I almost thought that it wasn't going to happen for me, so I'm very aware that I was blessed with that. It could have been something different."

Lopez was 38 when she and then-husband Marc Anthony started their family.

"I don't take it for granted one day," she said of her good fortune as a mother — and a particularly busy mother at that.

In addition to the usual mom duties, she's busy working on her NBC crime drama "Shades of Blue," recording a new Spanish-language album, preparing to star in the next NBC musical "Bye Bye Birdie Live!" and she has her very own Vegas show.

"It is a little bit insane," Lopez admitted. "I take it one day at a time. Me and the kids are like gypsies. We're traveling all over the place, just getting it done, doing the best we can."
