Jennifer Lopez had an emotional homecoming as she and husband Marc Anthony visited school kids in Jen’s native Bronx.

As pregnancy rumors swirled around her, she broke down in tears on stage!

“What did you do to me?” she turned and asked Marc. “Look at my makeup. I know, I’m a mess!”

But Jennifer swears she got emotional not because she’s pregnant or feeling maternal, but because it was a flashback.

She explained, “We were both crying. He [Marc] had glasses on, at least. You see yourself in the kids, you know, how far they can go.”
