The Cutest Celebrity Kids on Instagram

Suri Cruise made a rare public appearance at the Global Citizen Festival in New York City's Central Park, all in the name of a good cause. The 9-year-old joined her mom, Katie Holmes on stage, while she addressed the crowd of thousands.

The actress took to Instagram to share a sweet photo of her and her 12-year-old son Deacon Phillipppe against a picturesque forest backdrop.  "Let’s do this! Into the wilderness we go …. #StayWILD #HikingTrip," Witherspoon captioned the picture.

In a recent snap, Kardashian sits next to her little girl as they lounge in the sun and show off their windblown locks. The mom-of-three wears a Los Angeles Dodgers hat, cute crochet bikini top, and oversize aviator sunglasses, while her mini-me dons a navy one-piece swimsuit and delicate silver bracelet. "Mondaze," she simply captioned the photo.

Simpson took to Instagram with a photo of little Maxwell Drew that shows the little girl posing sweetly with a bouquet of freshly picked white blooms.
