Halloween just got a whole lot cuter!

We've seen a ton of sexy celeb costumes already this year, but it's the stars' adorable offspring that are stealing the spotlight!

Beyonce shared the sweetest snap with daughter Blue Ivy via Instagram on Friday. Little Blue's dressed up as the King of Pop himself, Michael Jackson -- and her famous momma matched, going as Janet Jackson.

"Janet and MJ," Bey captioned the adorable shot. Queen B's daughter even has her MJ pose down!

But not to be outdone, Neil Patrick Harris and his fabulous little family stole the spotlight this year again with their matching Marvel costumes.

Neil's dressed as The Riddler, while hubby David Burtka's rocked The Joker. Their adorable kiddies, Gideon and Harper, had matching  looks, dressing as Batman and Batgirl.

"Happy Halloween from Gotham City!!," the "How I Met Your Mother" star captioned the cute candid. Check out the gallery above for more of their amazing family costumes!

And Nicole Richie took the sweetest snap with her lookalike kids for the spooky holiday. Richie's rocking a Cruella De Vil costume while her children, Harlow and Sparrow, are dressed as adorable little dalmatians. "101 MADDENS," she cleverly posted along with the fun photo.
