While Julianne Hough’s Halloween costume faux pas drew the most attention at a star-studded Beverly Hills Halloween bash on Friday night, other A-listers wore more appropriate gear.

Leonardo Dicaprio arrived with a black cape to Mike Meldman’s annual bash, while Cindy Crawford and her hubby, Rande Gerber, made a convincing Slash and Axl Rose. Larry David and producer Bradley Thomas wore one giant cardigan sweater together and were “Siamese twins,” while Cuba Gooding Jr. came as Gerber, one of the night’s hosts.

Other guests at the Casamigos Day of the Dead-themed party included Alessandra Ambrosio, Ron Burkle, Jeremy Piven, Kate Upton, Jerry Weintraub, WME’s Patrick Whitesell, Ryan Seacrest, Sacha Baron Cohen and Sean Penn.

But Hough’s politically incorrect costume — she wore blackface as the character Crazy Eyes from the show “Orange Is the New Black,” in a group with pals — was a sour note.

She later tweeted, “It certainly was never my intention to be disrespectful or demeaning . . . I realize my costume hurt and offended people, and I truly apologize.”
