Justin Bieber's muscular dad, Jeremy Bieber, 49, goes shirtless to the beach with his wife Chelsey Rebelo, 35, in St. Barts… and reps his son's clothing line

Justin Bieber's dad Jeremy Bieber and his wife Chelsey Rebelo continued to enjoy some fun in the sun while vacationing in Saint Barthélemy this week.

The couple was photographed in recent days frolicking along the scenic beaches of the Caribbean island, an overseas community of France.

On Friday, the eldest Bieber gave a respectful nod to his famous son by wearing a pair of yellow swim trunks from clothing brand Justin's Drew.

Remaining shirtless all afternoon, Jeremy showed off his fit physique and his array of tattoos that cover much of his arms, chest and stomach.

Jeremy and Chelsey spent much of their time playing in the sand and ocean with their five-year-old daughter Bay, who seemed to be in heaven from the big beaming smile on her face.

On a number of occasions, Jeremy, 49, could be seen holding his daughter's hand as waves crashed onto the shoreline.

His wife, 35, who was also never far from Bay's side as she played along the sand, also showed off her fit figure in a yellow bikini.

Since they spent a lot of time swimming in the beautiful ocean waters, Chelsey chose to wear her dark locks long and flow down to the middle of her back.

At one point, the couple was spotted walking on either side of their daughter in the shallow ocean water that was only a few inches deep.

Jeremy documented their Friday together at the beach by sharing a photo of the couple with big smiles on Instagram.

“When a man and a woman come together, they are unstoppable!” the father of four said, in a reference to the romance.

The YouTuber was expected to return to the social media platform on Saturday to share some more love for his wife during their holiday in paradise

'10 years later, 5 years married, a lifetime to go. I love you @chelseybieber #stbarths,” Jeremy wrote in the caption of the post, which shows the couple snuggling up against each other with the beautiful blue ocean water in the background.

Together with Justin, Jeremy has two children – daughter Jazmyn, 15, and son Jaxon, 14 – with ex Erin Wagner, whom he dated from 2007 to 2014.

Jeremy then married his girlfriend Chelsey Rebelo in February 2018, and together they welcomed daughter Bay. Jeremy is also a stepfather to Chelsey's 16-year-old daughter Allie.

He divorced Justin's mother, Pattie Mallette, just ten months after she gave birth to the future global superstar following a rocky relationship.

According to Pattie's autobiography, The Only Way Is Up, the teens were actually engaged, but called off the wedding when Jeremy cheated on her with a mutual acquaintance.
