Madonna's Son Rocco Takes Brother and Sister Back to School—See the Cute Pic!

Plus, see pics of other celeb kids going back to school

Madonna's children are ready for another exciting school year!

The Material Girl shared an adorable twitpic of her oldest son, Rocco Ritchie, taking his younger siblings, David Banda and Mercy James, to their first day of class! "Dis how we do! Spicoli takes his little bro and sis to the Lycee! ❤❤❤❤❤❤ #proud," the pop star wrote.

If you're wondering where that nickname came from, the 14-year-old has been channeling Sean Penn's character Jeff Spicoli from 1982's Fast Times at Ridgemont High. The proud mom even posted a photo of the teen imitating her ex-husband in the hit film.

Other celebs like Brandi Glanville, Molly Ringwald and Candace Cameron Bure also shared their kids' cute back to school pics! Take a look!
