From Deacon Phillippe to Apple Martin: 16 celebrity kids that are all grown up.

Long before Instagram, the biggest celebrities of the 90s and 00s reserved their pregnancy announcements and baby photoshoots for magazines. We still remember THAT Vanity Fair cover where Katie Holmes and Tom Cruise showed off a newborn Suri Cruise (with a full head of jet-black hair.)

But fast-forward a decade or two and many of those babies are now teenagers who are learning to drive, finishing school and even following in their famous parents' footsteps. 

While some of their parents share their kids' birthdays and exciting milestones on social media, it's still a shock to see how much they've grown.

Watch: Here's what your favourite celebrities got up to in isolation. Post continues after video.

Earlier this week, Reese Witherspoon shared a photo of herself and her eldest son Deacon on Instagram. And the 17-year-old looks so mature it's frightening.

Apple Martin

On Monday, Gwyneth Paltrow told her millions of Instagram followers that she'd be launching some new Goop products. For the announcement, she shared a rare photo of herself and 16-year-old daughter Apple Martin.

And of course, she's the spitting image of her mum.

Leni Klum

Heidi Klum's daughter Leni not only looks just like her mother, but she's also getting into the same industry. In December 2020, the 16-year-old made her modelling debut alongside her mum on the cover of Vogue Germany.

Sharing the news to Instagram, Leni wrote: "So excited for my first cover!! I had so much fun on set with @voguegermany couldn’t dream of a better start!! Thank you for being by my side @heidiklum."

Speaking to People, Klum explained that she feels Leni's old enough to enter the industry.

"I always thought she was too young. We always also decided to keep the children out of the public eye. But she's driving a car now, she's 16, so I figured if you can do that, you can also model now if this is what you wish to do," she said.

Mercy James

Mercy James is Madonna's daughter, and was adopted by the musician at age 11. Now, she's 15!
