Justin Bieber and Hailey Bieber have welcomed a new furry member to their family. The couple got a new puppy named Piggy Lou and shared the photos on social media Tuesday.

Justin and Hailey already have a dog named Oscar, who they welcomed in 2018. And now, in the wake of the Halloween celebration, the couple welcomed their new puppy and dressed her in a piggy costume.

The 28-year-old Canadian singer shared the puppy's photo on Instagram Stories and wrote, "This is Oscar's new baby sister, Piggy Lou." He also shared a solo photo of Oscar, wearing a pink polka-dot scarf around his neck. The photo was captioned as "PIG."

A Twitter user shared the screenshot of the Instagram Stories on Tuesday:

Justin also shared a series of photos on Instagram featuring him as Sesame Street's Cookie Monster while Hailey, 25, donned a black vampire outfit.

In the first photo, the couple can be seen posing together alongside their two pets. In the next photo, Justin made a sad face as he cuddles one of his pups. Other photos also featured him hugging the doggies while Hailey posed for the photos.

The new addition to the family comes after the couple marked their four years of wedding anniversary in September. Justin and Hailey got married in September 2018 and this year, the singer shared a sweet post on Instagram.

He shared a black and photo of him and his wife laying down along with their puppy Oscar. "Happy anniversary to my best friend and wifey @haileybieber," the singer captioned the post. "Thank u for making me better in every way."

Hailey also shared a series of throwback photos from their wedding and other cute moments on Instagram in September and captioned the post, "4 years married to you. the most beautiful human I've ever known... love of my life. Thank God for you."

Aside from welcoming a new member to the family, Justin made headlines last week for visiting Churchome in Beverly Hills, California, with singer Shawn Mendes.

On the work front, Justin will lend his voice to an animated movie, titled "Cupid," which is currently under pre-production.
