Halloween is here … which means kids are putting on their costumes and their parents are grabbing their cameras to capture every moment — just like these celebrities’ parents did years ago!

We’ve gathered a collection of photos featuring celebs long before they became famous … when they were simply portraying characters on Halloween instead of performing on stage or screen.

Check it out … the witchy celeb on the left later played a magic-wielder on TV — and her songs are certainly enchanting, too. And, the little boy in the center grew up to be a Hollywood heartthrob … though Seth Rogen knows you wouldn’t want to be ‘Neighbors’ with this Joker!

This popstar may have been a princess back in the day … but she prefers a four-letter word to describe her actions these days. We’re sure the other little kids were as green as her album cover with envy when they saw her costume!

As for this witch … she infuses every project she takes on with a bit of magic — whether it be fashion, podcasting, or vlogging.

We’d guess these celebrities wouldn’t trade their lives for anything … but even they enjoyed dressing up as someone else back in the day!
