Leah Remini, a longtime pal of Lopez's, says there's hope Emme and Max, both 2, will get a little brother or sister, if Mom has her way.
"Jen would love to have more kids," Remini, 40, told PEOPLE at the 32nd Anniversary Carousel of Hope Ball, which benefitted the Barbara Davis Center For Childhood Diabetes.
Aside from mommy duty, Remini says Lopez, 41, is enjoying another one of her jobs: her gig on Fox as an American Idol judge.
"She loves it," says the star of The King of Queens. "This is one of her favorite jobs because Jennifer loves artists. Jennifer loves to find somebody. She's a fan of the show. Jennifer really wants to find 'it.' "
