AceShowbiz - Justin Bieber's friends apparently think that being a first-time dad may be too much for him. If a new report is to be believed, the "Ghost" hitmaker's pals fear that the singer may not be able to handle the stress of parenthood after welcoming his first child with wife Hailey Bieber (Hailey Baldwin).

"Justin already has a hard time coping with life in the spotlight, so the worry is the stress of having a child to take care of and protect will be more than he can handle!" an insider tells In Touch. "Hailey's been his rock - but now she's got to make being a mother a priority!"

Previously, it was said that the model had to calm her husband down from the proverbial ledge while she was pregnant. The source adds, "There are now worries the pressure of being new parents could push their marriage to the point of no return."

Fans, meanwhile, already expressed concern regarding Justin's well-being before he welcomed son Jack Blues Bieber last month. The Canadian star looked stressed when he traveled to India to perform at a billionaire's wedding back in July. He also lashed out at a group of fans who trailed behind him at a hotel in Beverly Hills.

"He used to enjoy his fans and all the attention that comes with his fame. But now it just seems to upset him, and the fear is part of that is all the pressure he's facing at home," a source claimed at the time.

In other news related to the Biebers, it was said that the couple received the help from Dr. Thais Aliabadi when Hailey delivered baby Jack at Cedars-Sinai Medical Center in Los Angeles on August 22. The doctor is the same obgyn that Khloe Kardashian and Kylie Jenner used to deliver their children.
