Jennifer Lopez asked her teacher mum Guadaloupe to accompany her on tour and tutor her four-year-old twins - so they are best prepared for kindergarten next autumn (13).
The pop star is currently travelling across the globe with the tots as part of her Dance Again World Tour and she invited her mother and cousin Tiana Rios to join her on the road and babysit them whenever she needed to rehearse.
And she got tutorial sessions thrown in for free - in a bid to ensure little Max and Emme - her twins with ex-husband Marc Anthony - don't miss a step in their studies due to life on the road.
Lopez tells HollywoodLife.com, "My mum was a teacher for 20 years - first grade, kindergarten and phys ed (physical education), and so my mum gives them a lesson every day. They're on our schedule - so they go to sleep late after the show, and they sleep late. They have to have 10 hours of sleep every night - that (is) critical to prevent crankiness.
"When they get up, they have breakfast, and then they go in with my mum for their lesson."
And Guadaloupe also takes them on educational field trips.
The singer adds, "Even my own family questioned my decision to bring Max and Emme on tour. But being with me is so much better than not being with me and wondering where mommy is... They look at maps, they know the world is big, they've learned different bits of languages.
"When I have a day off, it's all for them, and if I can't go out, they still go with my mum or their Aunt Tiana. They sight see. They get a lot more out of this tour of so many countries than I do. I see the hotel rooms, arenas and gyms."
