While Sarah Hyland and Wells Adams got musical by dressing up as David Bowie and Freddie Mercury, Demi Lovato went the sexy route with her insanely intricate Marie Antoinette costume (before she transformed into Pennywise the next day for another Halloween bash).
More stars showed up in their Halloween best for the Casamigos party in Beverly Hills. Nina Dobrev gave her own version of Billie Eilish, and Jessica Biel paid the ultimate tribute to husband Justin Timberlake‘s *NSYNC past.
