Justin and Hailey Bieber Celebrate Halloween in Style: See Their Costumes

The singer and his model and Rhode founder wife stepped out in style for Halloween on Saturday night

Justin Bieber and Hailey Baldwin Bieber are getting into the Halloween spirit.

On Saturday, the couple attended Vas J. Morgan and Michael Braun's Halloween Party in Los Angeles, California and they channeled The Flintstones for their spooky season attire, wearing costumes inspired by Pebbles Flintstone and Bamm-Bamm Rubble for the fun event.

Justin, 29, went shirtless and sported furry animal print fabric wrapped around his waist, which even featured a furry bone. The "Baby" singer added a backward yellow cap with black shapes printed on, similar to one worn by Bamm-Bamm, to complete his look.

Hailey, meanwhile wore a red bobbed wig, a patent cropped green Pebbles-inspired sleeveless top that featured black shapes, teamed with a blue and coral patent skirt that featured a bone detail and had a torn-effect hemline. The model, 26, made sure to include her "B" necklace in her Halloween look — the bling "B" likely represents her and her husband's shared last name and Hailey was recently spotted wearing it earlier this month.

Ahead of their couple's night out, Justin also celebrated Halloween when attended the Casamigos Halloween Party in Beverly Hills on Friday. For the event, he wore a fun, beach-inspired outfit that included a snorkel mask and flippers, a print shirt and a pair of print shorts.

Meanwhile, his wife teased two stylish Halloween costumes on Instagram earlier this month. In a photo dump post from Oct. 18, Bieber revealed two looks — a sexy vampire and a '90s fashion girl.

While vampires might be a Halloween classic, Hailey put her own spin on the look with a lacy corset with attached sheer sleeves. She paired the top with a velvet skirt and thigh-high stockings. Of course, no vampire would be complete without a little blood, and Hailey's drop of red liquid at her lip added a spooky touch.

The model's nostalgic '90s look saw her posed in a black turtleneck and plaid mini skirt. She finished off the look with a low-maintenance updo, white socks and loafers and a cup of coffee, hinting that the look was inspired by Jennifer Aniston's character, Rachel, from the '90s sitcom Friends.

Hailey made headlines earlier this month when she commented on her and husband Justin's mismatched styles. Justin gets ready first, Hailey said, and she might dress in a different vibe "just because that’s how I’m feeling.”

Hailey and Justin celebrated their fifth wedding anniversary this year and the singer gushed about his bride on Instagram, writing, “You have captivated my heart. I know from the depths of my soul down to my bones that this journey with you will only exceed our wildest expectations.”
