The Glee star and the Hollywood couple dressed up in traditional German costumes as they attended Kate Hudson's star-studded Halloween party in the Pacific Palisades Saturday night, where guests snacked on pizza from Italian restaurant, Terroni.
Kurt donned a white wig, lederhosen, a shaggy white beard and a cap and carried a walking stick, while Goldie looked like either one of the von Trapps (from the The Sound of Music) or a bar wench wearing a blond wig with long German braids and a pink bonnet and dirndl.
The latter is a classic Bavarian dress featuring a skirt and low-cut white blouse.
The longtime partners were all smiles as they turned up at Kate's estate and mingled with other guests. Hudson, Goldie's daughter with actor Bill Hudson, invited a who's who of famous pals including Michele, who in her German-themed outfit appeared ready to belt out her best yodel.
Other celebs in attendance included Fergie and Josh Duhamel as Elvira and Riff Raff from The Rocky Horror Picture Show; Bad Grandpa star Johnny Knoxville as Liberace; Dancing With the Stars hoofer Derek Hough as a mohawk-sporting punk; Paris Hilton sticking out her tongue as Miley Cyrus from her notorious MTV VMAs performance; and David Spade who we can only guess is offering up his best impression of the Fantastic Mr. Fox.
