The stars dress up as icons, favorite characters and even each other

Halloween has not even taken place yet, but we already know how our favorite celebrities mark this year's festivities.

Indeed, over the weekend, the stars disguised a little early for several big games – and they did not stop.

Trust us, some of these costumes will make you double taking!

One of the biggest celebrations in Tinseltown was the Casamigos Halloween Party, and the men who founded the tequila label, George Clooney and Rande Gerber, were present at the event.

A-list and businessman showed off their matching pilot suits, while Gerber's wife, top-model Cindy Crawford, brought a retro look as a "business man". air hostess of the old school.

Also present were Kendall Jenner, who channeled her inner fembot "Austin Powers", and the star of the romantic comedy Noah Centineo as the favorite baddie of all, Gaston.

But the best costume of the bash had to be the one worn by Harry Styles, in which the singer was a deadly bell ringer for another superstar singer – Elton John.

Styles was far from the only star to pose as another famous face. In fact, it was rather the trend during other shows and celebrations.

From the amazing transformation of Rita Ora into rap star Post Malone:

Ariel Winter and Levi Meaden take over ex-couple Pamela Anderson and Kid Rock:

Joe Jonas holiday transformation into … his own fiancée?

Yes, the singer-actress is disguised as Sophie Turner's character, partner of "Game of Thrones". (Be sure to click or swipe to see the other outlet that he has shared for a complete fun effect.)

Although there are no ghosts or ghouls among these famous faces, there were two classic costumes in the mix.

For example, Jerry Seinfeld is disguised as Big Bad Wolf (disguised as grandmother) alongside Red Riding Hood of his wife Jessica.

And two stars have not only been classics, but they have also brought their children.

John Legend played Prince Charming for his two-year-old princess Luna.

While Pink came out as a marine mum with her pirate boyfriend, her 22-month-old son, Jameson.
