"But the one that connects me and her is 'You Are My Sunshine.' She sang that to me every day when I was little when I was going to sleep."
Emme is an incredibly talented singer and impressed fans when she got up on stage with her mum in February at the Super Bowl halftime show.
Jennifer and Alex can't wait to get married
The pre-teen admitted that she doesn't get too nervous about singing in front of crowds, telling People: "I just don't overthink it. I get up there and do it."
Jennifer and Alex got engaged in 2019, and J-Lo admitted to being a "little heartbroken" that their day couldn't go ahead as planned, because they had "some great plans" for it.

Talking on the Today Show in May, the Let's Get Loud hitmaker said: "You just have to kind of wait and see how this all plays out…
"I’m a little heartbroken because we did have some great plans but I'm also like, you know what, God has a bigger plan, so we just have to wait and see."
Jennifer and Alex's children will all have a special role in the ceremony when it does go ahead.
