Happy October, gossip fans! It’s the spookiest, glitteriest, most fabulous time of the year.

You’d think that celebrities would get sick of dressing up in costumes–since they do that every other day of the year–but plenty of famous folks trotted out impressive Halloween looks this year. Can you guess who they are?

Marilyn Manson & Violent J

Evan Peters and Halsey

This couple went all out for Halloween, dressing as a pitch-perfect Marilyn Manson and Violent J from Insane Clown Posse.

The next day, they dressed up as Sonny and Cher! Can you guess who this is?

It’s American Horror Story actor Evan Peters and Halsey!

Sexy Pennywise?

Demi Lovato

There are those who would argue that Pennywise the clown is already sexy. However, this pop star took things to the next level with her lacy, leggy version of the villain.

That’s Demi Lovato under all that spooky makeup and ruffles!

Paging Ms. Naughty Nurse

Cardi B

Okay, this one isn’t too hard to guess. Honestly, this rapper would probably wear a similar outfit to the Grammys–or to pick up vitamins at the drugstore.

It’s none other than Cardi B!

Wubba Lubba Dub Dub!

Camilla Mendes

This actress wanted her fans to know that she used lime-green glitter to recreate Rick’s distinctive vomit dribble. That’s some dedication to detail right there. But should any character from Rick & Morty be this sexy?

Riverdale star Camilla Mendes, you win the award for the most upsetting costume this year!

You Will Seriously Never Guess Who This Is

Kathy Bates

While her werewolf costume isn’t that creative, we’re delighted to see this Oscar-winning veteran actress get into the spirit of Halloween. We’ll give you one more clue–she once starred in an adaptation of a Steven King novel.

That’s the legendary Kathy Bates!

So Billie Eilish Just Dressed as Herself?

Nina Dobrev

Friends, that is not the real Billie Eilish. Instead, it’s an actress who absolutely nailed the hair, clothing, makeup, and mannerisms of Billie at the Casamigos Halloween party (thrown by Cindy Crawford and Rande Gerber).

It’s actually Vampire Diaries star Nina Dobrev!

Faux JLo

Lisa Rinna

Also attending the Casamigos party this year was JLo… no, wait, that’s actually an actress-turned-reality-star you might remember from The Real Housewives of Beverly Hills.

Lisa Rinna absolutely nailed this costume–and she looks great for 56!

It’s Gonna Be Me

Jessica Biel and Justin Timberlake

Couples’ costumes are so tricky. Most of the time, they end up cheesy or fail to make any sense unless the two of you stand next to each other all night.

This mega-famous duo decided to go all out–but honestly, she’s the star of the show. Do you know who this is?

It’s Jessica Biel dressed as her husband… and Justin Timberlake as a microphone!

Um, Aren’t We Over the Joker and Harley Yet?

Nikki Minaj and new husband

These newlyweds decided to go for the classic Joker and Harley couples’ costumes. I’m not saying they look bad–but everybody already did this look in 2016 when Suicide Squad came out. You get an “A” for effort, but maybe try something fresher next year.

Oh yeah, this is Nicki Minaj and her husband, Kenneth Petty!

Last, But Not Least…

Stormi Webster dressed as mom Kylie Jenner

This adorable little nugget is dressed up like her mama this year. Honestly, she looks a little uncomfortable, but it’s a really impressive costume.

It’s Stormi Webster, in costume as Kylie Jenner at this year’s Met Gala!
