A ton of stars got the jump on Halloween this weekend, with costume parties going down in Los Angeles on Friday and Saturday night.
While celebs like Hilary Duff, Cindy Crawford, Tim Allen and more got wild at the Casamigos bash in L.A. on Friday (see those photos here), even more got crazy at "Glee" star Matthew Morrison's birthday/Halloween soiree the following evening.
This is the fifth time the actor has held a costume party to celebrate his b-day, this one going down at Hyde Los Angeles.
Morrison and new wife Renee Puente dressed up as John Travolta and Uma Thurman's characters from "Pulp Fiction" -- and were surrounded by friends with equally inventive costumes. Celebs dressed as superheroes, animals and Riff Raff from "The Rocky Horror Picture Show" all made appearances as the bash, but none was as impressive as the actor who went as Princess Fiona from "Shrek."
Covered in green paint, this actor was totally unrecognizable at the party. Who is he? Find out in the gallery above!
Matthew's wife sang "Happy Birthday" to the actor for his 35th birthday, while Adam Lambert was on stage to perform Queen's "Another One Bites the Dust' for the crowd. Sounds like a pretty fun party, right?
Check out all the party pics above, plus photos of even more celebrity costumes this year!
