Jennifer Lopez has made no secret of the fact that she loves being a mom — and the more the merrier.
Crediting her 11-year-old twins Emme Maribel and Maximilian “Max” David with teaching her the meaning of true love, she has also embraced being a supportive presence in the lives of fiancé Alex Rodriguez‘s two daughters: Ella Alexander, 11, and Natasha Alexander, 15.
“We all just grow closer,” Lopez tells PEOPLE in this week’s cover story of her happy blended family with the MLB legend, 44. “When we got engaged, they were super happy … they know there is nothing but love for them always.”
“I don’t know that it’s in God’s plan but I would like to try. I’m so open to it!” she adds.

For Lopez, raising Emme and Max, her kids with ex-husband Marc Anthony, changed the trajectory of just about everything in her life.
“They made my life so much better [and] them being born led me in a different direction,” she says.
“I was being careless with myself, and my heart,” Lopez adds. “The kids kind of snapped me right [out] of it because I felt so much responsibility and love for them. Love first and responsibility second. I just knew I had to be better.”

And despite juggling a dizzying schedule and enjoying a banner 2019 in her career, Lopez says the kids are her and Rodriguez’s priority and “our No. 1 job.”
“We try to raise the kids in a way that’s mindful of fulfilling our own dreams but also never being in a position where they’re not being guided by us or we’re not present in their lives … that’s a priority,” she shares.
