Halloween isn’t just for kids, you know. Every now and then adults like to dress up in all sorts of characters too – including many of our favorite celebs. Some are a little more creative than others.

Check out a few of the hottest costumes from 2016. You can’t help but wonder what they’ll pull off this year!

Gwen Stefani: Our favorite girl next door, Gwen Stefani and her son, Zuma took to Instagram to show off their post apocalyptic zombie get up.

Keke Palmer: Last year, Keke paid homage by going dressed up as Selena Quintanilla.

Serena Williams: No one’s really sure what Serena’s costume was last year, but the best guess is that she was an 80s fitness instructor.

Victoria Justice: Bet you won’t say Beetle Juice 3 times fast! If so, Victoria Justice might appear. The singer and actress dressed up last year as the ghost with the most in a beetle juice costume.

It’s beautiful when a couple gets into the Halloween mood together. For example, Leanne Rhimes and hubby Eddie Cibrian. They both dressed up last Halloween as the 1980s version of Madonna and George Michael.

Trevor Noah: Last year, Trevor Noah dressed up as Prince Akeem from “Coming to America”.

La La Anthony: Our very own, La La Anthony gave us a fright in her zombie bride costume. She looked better than most – even with the extra blood.

Rihanna: Leave it Rihanna to push the envelop! She pulled off her Halloween costume perfectly as a Teenage Mutant Ninja Turtle.
