On Saturday, the couple visited Vas J. Morgan and Michael Braun’s Halloween Party in Los Angeles, California and they emulated The Flintstones for their scary season outfit, wearing costumes inspired by Pebbles Flintstone and Bamm-Bamm Rubble for the fun event. The 29-year-old Justin went shirtless and wore furry animal print material, complete with a furry bone, around his waist. The “Baby” singer wore a backward yellow cap with black shapes printed on, similar to one worn by Bamm-Bamm, to complete his look.

Hailey, on the other hand, donned a red bobbed wig, a patent cropped green sleeveless shirt with black forms inspired by Pebbles, and a blue and coral patent skirt with a bone accent and a torn-effect hemline. The 26-year-old model made care to accessorise her Halloween ensemble with her “B” necklace, which she was recently seen wearing earlier this month. The bling “B” probably symbolises her and her husband’s common last name.

Justin celebrated Halloween by going to the Casamigos Halloween Party in Beverly Hills on Friday, one day before their couple’s night out. He dressed for the occasion in a playful, beach-themed ensemble that included a print shirt, a pair of print shorts, a snorkel mask, and flippers.
