Jack Osbourne and his daughter jumped on the crazy train to honor Ozzy Osbourne.
Over a year after the Black Sabbath rocker died at the age of 76, the 40-year-old and his daughter Pearl, 14, went undercover at Universal Halloween Horror Nights, scaring fans at the Ozzy Osbourne: Prince of Darkness haunted maze at Universal Studios Hollywood.
As shown in the footage, the former reality star—who shares Pearl with ex-wife Lisa Stelly—and the teen were transformed into bloody, bat hybrid creatures, wearing priest costumes, scary makeup and horrifying masks.
