The Hollywood stars and celebrity kids taking over TikTok

Forget Snapchat, Vine or Instagram. These days, all the cool kids are using the new social media app, TikTok.

The video-sharing platform is often described as the lovechild of Snapchat and Vine — users can film, edit and share 15-second videos and pimp them out by adding filters, music and special effects.

It's all the rage — even celebrities and their kids are jumping on board. Take a look...

Leo Reilly

Thanks to Huffington Post writer Zeba Bay, who pointed it out on Twitter, we just discovered actor John C. Reilly's model son!

His dad may be famous but Leo is TikTok famous. Scroll through his account and you'll get lost in all his cool content. Or you may just get lost in his eyes...

Miley Cyrus

Username: @mileycyrus

Miley Cyrus is a newcomer to TikTok but she already has 2.6 million followers. Catch her just being Miley as she posts videos of herself lip-syncing and dancing on the app.

Jessica Alba

Username: @jessicaalba

The mum-of-three refers to herself as 'Yo Mama' on TikTok. But you're mistaken if you thought her account was full of mumsy videos — the actress drops plenty of dance clips, proving she can totally kick it with the cool kids. She did slice up the floor in the dance movie Honey, after all...

Romeo Beckham

Username: @romeob7

David and Victoria Beckham's son, Romeo, boasts 282.8K followers on TikTok. No doubt he scored a whole new following after he posted a video of himself and his Posh mum dancing to 'Spice Up Your Life'. The former Spice Girl also shared the video on her Instagram account.

Jaya Harper

Username: @jayaharper

Jaya Harper is in danger of being outstaged by her famous mum, Laura Dern. In December, the Oscar winner interrupted one of Jaya's videos, pushing the 15-year-old aside to bust out some moves.

Coco Arquette 

Username: @cocoarquette_

Coco Arquette often features her mum, Courteney Cox, on her account. And the 15-year-old can't help but troll the actress over her inability to understand the app. 

"Wanna see your child lose their patience? Do a TikTok with them," Cox said of one video of the pair, which she shared on Instagram.

Jennifer Lopez

Username: @jlo

That saucy performance Jennifer Lopez put on during the Super Bowl Half Time show? There's plenty more where that came from. The star's account is full of dance routines, which some followers have replicated in their videos, sparking the hashtag #JLoTikTokChallenge. 

Mason Disick

Username: @mason_disick

Kourtney Kardashian and Scott Disick's son, Mason, is fast becoming TikTok famous. It helps that his parents make cameos in his videos every now and then. That may explain why the 10-year-old has 68,000 followers... and counting. 

Although, you can only catch glimpses of Mason's videos whenever his parents share it to their Instagram accounts — his TikTok is set to private.

5 Seconds of Summer

Username: @5sos 

The Aussie boy band love to showcase their new music on TikTok, but their half-a-million followers are also hooked on the group's backstage antics. 

Iris Apatow

Username: @irisapatow

Director Judd Apatow gets in on the silly fun over on his 17-year-old daughter Iris' TikTok. Most recently, father and daughter mimed their way through a video, while dropping swear words. 

Jimmy Fallon

Username: @jimmyfallon

Jimmy Fallon posts clips from The Tonight Show on his TikTok. But it's the videos he shares behind-the-scenes from the show that landed him almost one million followers. 

Usher 

Username: @usher 

OK, so R'n'B singer Usher only has one video on his account, but it's one worth hero-ing. The hand signs challenge that went viral on TikTok was difficult for many users to muster, but not Usher. Nail it!
