Justin and Hailey Bieber Step Out for Date Night at Friend Lauren Perez’s Bowling Birthday Bash in Beverly Hills

Justin Bieber and wife Hailey Bieber kept it casual to celebrate a friend.

The couple was spotted out on a date night as they attended fashion consultant Lauren Perez’s 33rd birthday bash at Lucky Strike bowling alley in Beverly Hills, Calif., on Saturday, Jan. 4.

As they left the venue in the early hours of Jan. 5, Justin, 30, was seen sporting a black jacket, white shirt, baggy plaid pants, a black beanie and glasses, while Hailey, 28, wore casual blue jeans and a brown jacket.

Perez’s longtime friend Kendall Jenner also attended the party. The Keeping Up with the Kardashians alum, 29, was spotted wearing a casual red collared shirt and black pants with a black purse and black flats.

The photos of Justin and Hailey’s date night come on the same day the singer shared an affectionate Instagram photo of he and his wife.

In the photo, Justin cuddles up to Hailey’s neck and plants a kiss there.

The selfie was posted just days after Hailey addressed social media rumors that the new parents, who welcomed new son, Jack Blues, on Aug. 23, were experiencing marital troubles.

On Dec. 30, the new mom appeared to address online rumors regarding an alleged strain in her relationship with Justin by reposting a viral TikTok in which a user says, “You’re not well, and it’s okay.”

“[M]e to all of you on the internet,” she wrote over a repost of a viral clip, adding a hand heart emoji.

This isn't the first time the couple has dealt with rumors surrounding relationship problems or a possible divorce.

“They laugh at the constant divorce rumors,” a source said of the pair in November. “It’s annoying but just noise.”

On Dec. 16, Justin also shared a snap on Instagram showing Hailey kissing him on the neck in a sweet selfie.

"💕🙈😛🫶🏼," Justin captioned the photo.

The photo was seemingly taken around the same time as Justin's previous carousel of images shared on Instagram, which appeared to document the couple's weekend in Costa Rica for Perez's brother's wedding.

"They attended a wedding but also had special alone time," a source told PEOPLE at the time. "They seemed very happy."
