Star Magazine suggests that Justin’s parent’s relationship might not be so great. This was especially true when, while Justin was just 2 months old, his parents went through a bitter custody battle to gain control over him.

Flirting with Tina Fey on Saturday Night Live or talking about his crush on Beyoncé, Justin Bieber is loving his moment in the spotlight. But it hasn’t always been good times for the Canadian singer and his family!

In the June 14 issue of Star, which is on sale now, we report that Justin’s parents — Pattie Mallette and Jeremy Bieber — were embroiled in a vicious custody battle over him when he was just a baby.

According to legal papers obtained exclusively by Star, Pattie — who was just 17 when she became pregnant — and Jeremy, then 19, attempted to live together when Justin was 2 months old, “but ultimately those efforts failed” after four months, she said. A nasty custody battle followed — in which Pattie laid bare what she claimed were Jeremy’s demons, including his history of “criminal activity.” Local records show that Jeremy has had multiple arrests and jail time for “assault causing bodily harm” and “breach of probation.”

Pattie was given custody in May 1995 and allowed Jeremy time with their son. But when he went to court in December 1996 to ask for increased visitation and overnight stays with Justin, Pattie went on the offensive. Overnight visitation was “inappropriate,” she alleged in the court papers, because Jeremy was dealing with “uncontrolled violent behavior” and “alcohol and drug abuse.”

Wonder if their bad relationship has shaped who he is. It’s kinda sad.

In less than a year, Justin Bieber has gone from internet sensation to full-blown pop star. And, the 16-year-old stopped by “The Oprah Winfrey Show” on Tuesday (May 11) to admit that he’s still trying to comprehend his fame and success.

“It’s been pretty crazy coming from a little town in Canada and now being able to travel the world and do what I love,” he told Oprah. “I was just posting videos online for fun. I never really thought this was possible, so I never really dreamed of it.”

“He’s got such a great team of people around him,” his mom, Pattie, said on the show. “[They] protect his character and treat him like a kid and make sure that he stays grounded and has fun. I think I would worry more if he was in high school where I wouldn’t know what he was doing, whereas now I know who he’s with and where he is all the time.”

Bieber, who is currently filming a video for “Somebody to Love,” is quick to add that the people in his entourage are a tight-knit set and that he’s careful about who is added to that group. “We’re really skeptical who we let on our team. We’ve grown to be kind of like a family. It’s been incredible,” he explained.

To ensure that he isn’t too inundated by the trappings of his new superstardom, Bieber takes off one day a week to be a normal kid.

“We try to take off at least one day a week for me to be a regular kid, go play basketball, hang out with my friends and, you know, just do what I like to do,” he explained. “Sometimes for that day I just sleep all day because the six days before I’m exhausted.”

And while he usually spends his off days doing more “normal” things like basketball, sometimes he also gets the normal treatment when his mom grounds him.

“My mom takes things that I really like, like my computer, my phone. She takes my phone away for a couple of days and I’m like, ‘Oh, I need that!’ ” he said, adding there’s no way he could get out of it by saying that he’s Justin Bieber. He added, “She’ll slap me in the face!”

But, unlike most teen boys, they don’t have screaming girls following them everywhere they go. “It’s pretty hard to comprehend. Like everything’s just kind of surreal,” he said, adding “I have no clue!” why they scream at him.

Justin Bieber not only knows how to woo the ladies, but he also knows how to treat his mom on Mother’s Day.

Bieber caused quite a stir Sunday as he took his mom shopping at The Grove mall in Los Angeles.

“I’m here shopping for my mom to celebrate Mother’s Day,” Bieber told E! News when asked why he was standing in the all-female clothing store chain, Forever 21.

The singing sensation, who was also accompanied by a bodyguard and a male friend, managed to blend in with the crowd at first, sporting jeans, sneakers and a white t-shirt.

But according to an eyewitness, his cover was soon blown.

“Young female shoppers quickly realized it was him and started whipping out their cell phones to take pictures from afar,” an eyewitness told E! News. “He was super easygoing with it all and was smiling the whole time.”

Bieber and his mother left the store empty-handed, but they continued to shop and hang out at the outdoor mall, stopping at Guess and grabbing lunch at the Cheesecake Factory. The teen sensation even managed to work in some skateboarding.

Justin Bieber is 16-years-old, one of the biggest stars on the planet, and strangely enough, the Canadian crooner comes off as remarkably grounded and collected. So, on this Mother’s Day, PopEater had the opportunity to briefly chat with the teen star about his mom, their relationship and what it’s like to have her on the road with him as he zigzags around the world — dodging mobs of feverish girls everywhere he goes. That, and he also drops a tidbit about his romantic ways that’s sure to only feed the frenzy.

What did you get your mom for Mother’s Day?

I plan on making a special day for my mom – I already sent flowers. Maybe I’ll send her to a spa for the day to pamper herself.

What’s it like having your mother on the road with you?

It’s great – she’s a piece of home I get to take with me.

What’s the best advice your mother ever gave you?

Stay humble.

There are millions of girls always trying to get your attention. Are you the romantic type, buying flowers and such?

I have my romantic moments – for sure.
