Justin Bieber is once again making headlines, this time for a string of rather bizarre social media posts on his first Father’s Day.

The pop star, who welcomed his son Jack Blues Bieber with wife Hailey Bieber in August 2024, marked the occasion with a series of photos and eyebrow-raising captions. “I'm a dad that's not to be f--ked with 🖕,” Bieber wrote alongside images of himself with a middle finger emoji.

Sharing another close-up shot of his tattoos, he wrote, "quit f**king with me I’m really not the one."

In a series of photos, the singer shared images of himself and wrote, "Made it home from a lil date night getaway." He also went on to show off his new purchases that included a diamond-studded watch and a new luxury sports car. "Happy daddy day to me u lil ho," he captioned the photos.

He also went on to post photos of little Jack trying his hand at the piano and joining him for some playtime. However, he captioned the post with a middle finger emoji that left many confused.

The social media posts come just a day after the “Baby” singer lashed out at paparazzi outside Soho House in Malibu. When a photographer wished him a happy early Father’s Day, Bieber snapped, “I don’t know you. You don’t go to people you don’t know and say s--t out of nowhere with a camera in their face.”

He further scolded the photographers for allegedly trespassing, saying, “I’m a father. I’m a dad, and you guys are on private property in front of my car.”

Fans have grown increasingly alarmed over Bieber’s recent online behaviour, which includes posts about feeling drained by “transactional relationships.” Just last week, he wrote, “If I have to do something to be loved, that’s not love,” sparking speculation about the state of his personal life.

Despite public concern, a representative for Bieber has previously denied rumours that the singer is using drugs, insisting his behaviour is unrelated to substance abuse.
