Hailey Bieber and Justin Bieber adopt a dog named Piggy Lou Bieber

Hailey and Justin Bieber have a new member of the family.

On Tuesday, the 25-year-old supermodel and her husband, the singer of the superstar, 28, announced on Instagram that they have adopted the little dog Piggy Lou Bieber, a girl.

They are already fur parents to their Maltese Yorkie named Oscar, who they adopted in December 2018 shortly after their wedding.

Hailey called him “my Christmas baby” and Justin nicknamed him “dogson.”

The new little four-legged friend was featured in Hailey’s Instagram Stories.

Hailey shared a photo of the little dog dressed as a pink pig for Halloween, saying, “This is Oscar’s new sister Piggy Lou Bieber.”

She added a smiling emoji and two white hearts.

Justin held up the cute little beige dog wearing a pink pig outfit for Halloween as he lay down by their kitchen.

The two also shared several photos of them posing with both dogs as they seemed to enjoy being the parents of two small dogs.

Oscar was dressed as Oscar the Grouch from Sesame Street.

This comes after they had a fun night together at The Peppermint Club in West Hollywood on Sunday.

She was dressed as a Versace vampire and he as a Cookie Monster.

Hailey looked nothing short of sensational in a black bra with harness and criss-cross straps, showing off her great assets.

She paired it with a short miniskirt that showed off her tight legs to the fullest and wrapped a black belt around her waist to tie her in.

She added a gold “Versace” necklace around her hips and a chunky gold choker around her neck.

Hailey added a pair of black chunky knee-high boots and a gold garter belt around her thigh, while carrying a black handbag.

She hid her eyes behind oval sunglasses and also wore huge dangling pearl earrings.

Wearing a long black wig and a dab of red lipstick, she added teeth and a drop of blood from her mouth to complete the vampire look.

Meanwhile, Justin took a much more relaxed approach, opting for a blue Cookie Monster onesie and white trainers.

Hailey took to her Instagram Stories to show off the look, complete with black latex gloves and purple eyeshadow.

The founder of Rhode Skin left little to the imagination the night before when she attended Vas J Morgan’s Halloween party with her husband in tow.

Hailey looked sensational as she copied a runway look from the YSL Spring/Summer 1999 runway show.

Hailey wowed in a barely there costume of pink roses and vines with a sheer array of pink ruffles.

Making sure all eyes were on her, the beauty added inches to her body in towering heels and styled her long locks in luxurious waves, crowning herself with a floral headpiece.

The couple’s Halloween weekend comes in the wake of Justin’s doctors diagnosing him with Ramsay Hunt syndrome, which “occurs when a shingles outbreak affects the facial nerve near one of your ears,” according to the May Clinic.

In addition to the painful shingles rash, Ramsay Hunt syndrome can cause facial paralysis and hearing loss in the affected ear.

The syndrome has sidelined Justin’s music career for now, leading to the Grammy winner pulling the plug on his Justice World Tour in September, citing he wanted to prioritize his health.
