‘X Factor’ Maplewood teen grieves separation of moms

HAPPIER DAYS: Beatrice Miller grew up with two mothers and 10-year-old Vietnamese twin sisters in New Jersey.

HAPPIER DAYS: Beatrice Miller grew up with two mothers and 10-year-old Vietnamese twin sisters in New Jersey.

Competing on “The X Factor” provides a much-needed distraction for New Jersey singing sensation Beatrice Miller.

The Maplewood teen — whose neighborhood sustained extreme damage from Hurricane Sandy — has been privately grieving as her two mothers sort out a painful separation.

“I remember when I was 11 being in the car with them and they said ‘We can’t live together anymore,’ ” she tells The Post.

“My heart just crumbled. It was the worst moment of my life.”

Two years later, neither of her parents has moved out of the four bedroom colonial home they share with Beatrice and her 10-year-old adopted Vietnamese twin sisters.

“Normally when parents are divorced they don’t live together,” the eighth-grader says.

“Sometimes when they are in a huge fight I feel like I have to take responsibility for [twins Esther and Georgia]. It is just really difficult at home, and it has been for a really, really long time.”

Singing, Miller says, “is really the only thing that I can use to get away from all of the things that are going on in the house.”

A voice-over actress with credits in “Toy Story 3” and “The Wonder Pets,” Miller was conceived with the aid of a sperm donor, whom she never met.

“Bea is okay with her life,” says her mother Hilery Kipnis, a former producer for “The Oprah Winfrey Show.” “That is why she talks about it. She doesn’t feel like she has to hide it.”

But classmates weren’t always accepting of her unique family situation.

“In elementary school, people were like ‘What’s wrong with her?’ and that was hard,” Miller says. “Sometimes I got bullied, and I had to be the tough girl.”

A straight-A student, who dreams of directing movies, Miller is a member of “X Factor’s” youngest team, mentored by pop princess Britney Spears.

“Britney knows what she is talking about with the teen category because she was once one of us,” Miller says. “She knows exactly how to handle that and is a great mentor.”

Many think the young Avril Lavigne-in-training — with her funky rock-star wardrobe and colorful wristbands — could pose a threat to fan favorite and fellow middle schooler, Carly Rose Sonenclar.

The two girls have already gone head to head at many New York theatre auditions.

“I never actually thought to talk to her or knew her,” Miler says. “Then when I saw her at ‘X Factor,’ her mom said that she had auditioned for lots of Broadway shows.”

Raised in Brooklyn until age 4, she broke into show business in 2007 when her other mother, Kim Miller, a stage manager at CBS, passed head shots of all three children on to an assistant director at “The Early Show.”

Within weeks, she had her first audition.

“We weren’t really interested in our kids doing that,” Kipnis says. “I feel like everything in Bea’s career kind of fell into our lap. We never pursued anything. We did ‘X Factor’ on a whim.”

Kipnis says she woke up at 4 a.m. to get in line for a cattle call audition in Providence, RI, last spring, while the teen slept in her hotel room.

She has since accompanied the young singer on every step of the journey.

But both parents were in Los Angeles last night to watch their daughter perform live for the “X Factor” judges.

“My parents don’t really have time to fight about anything (right now),” Miller says.

“All they really have time to do is make sure I am out there doing what I need to do.”
