The 42-year-old, who recently finished a new movie "What to Expect When You're Expecting", was moved after working with a pair of twins who had been adopted from Ethiopia after their mother died on the film, reported Mirror online.
"It's funny because before the movie I never really thought about adoption, I just always wanted to have my own baby and I was so focused on that and it took me a while to have my own.
"But after the film and during the making of the film when I held those two little Ethiopian twins I fell in love instantly and I can see how somebody can do this, how it is so easy to embrace a child who has nothing.
"It's a beautiful, selfless act of love and it's something that you go, 'OK, I understand these feelings, I get this. I almost took those babies home. I fell in love with those babies," she said.
However, Lopez, who is dating backing dancer Casper Smart, said she is kept busy raising Max and Emme. "Adoption would be a blessing but I'm focused on doing it right with those two and I've really got my hands full."
