Demi Lovato and Camp Rock co-star Alyson Stoner reveal how they ended their feud for Child Star documentary

Camp Rock co-stars Demi Lovato and Alyson Stoner have revealed how they ended their feud for their upcoming documentary Child Star.

Demi, 31, landed her breakout role on Barney & Friends at age eight and became a Disney Channel personality shortly after.

As she grew into an adult celebrity, she faced a number of personal demons, including bulimia, substance abuse, and bipolar disorder.

Now she makes her directorial debut with Child Star, in which she interviews the likes of Drew Barrymore, JoJo Siwa, Christina Ricci and more about what it’s like to grow up as a celebrity.

She even arranged an on-camera interview with Alyson, but the couple had to patch up a long-standing rift first, they said The Hollywood Reporter.

The interview was accompanied by a sultry photoshoot starring Demi, who bared her cleavage on the cover of the magazine.

Demi, who uses both the pronouns “they” and “them,” showed off a series of glamorous, nude outfits with her best fiery femme fatale look.

One of her most striking outfits was a pinstripe suit that she wore without a blouse, leaving her black bra visible to the camera.

In the interview, she and Alyson reflected on the stumbling blocks they faced in their relationship — and how they eventually made amends.

Demi was 15 and Alyson 14 when Camp Rock first aired on Disney Channel in 2008, starring the two and the Jonas Brothers.

Two years later, they reunited for Camp Rock 2: The Final Jam, but on that project, Alyson struggled to work with Demi.

Demi struggled with drugs and body image, resulting in irritable behavior that left Alyson “walking on eggshells” around her.

“There was definitely a lot of fear of an explosion,” Alyson said during the interview for the documentary.

When they went on tour to promote Camp Rock 2, things between them didn’t improve and they didn’t speak for years.

While working on her new documentary, Demi reached out to Alyson, who is non-binary and prefers the pronoun “them.”

Demi had to assure Alyson that she had changed over the years before her former co-star agreed to an interview for the project.

She and Alyson had an off-camera conversation, which Alyson described as “healing,” before the recorded interview took place.

Alyson also had other reservations about the project, namely “that it would fall under the umbrella of sensational E! True Hollywood stories that would then essentially perpetuate what I call the toddler-to-train-disaster pipeline.”

Demi was able to ease her concerns and she spoke to Alyson about the trials and tribulations of being a child star.

Alyson and Demi reacted to each other when they saw their photos being digitally altered in magazines when they were still minors.

They also remembered that they had to carefully “align” with the branding of the brand-new Disney Channel personalities, unlike the teens on Nickelodeon, who Demi envied because they were allowed to be just a little bit more sassy.

Demi explained that her “traumatic” experience as a child star led to her problematic attitude during the filming of Camp Rock 2.

“I think about the people in the wardrobe department on my TV show, because I used to go there feeling grumpy. I also worry about the guest stars that showed up, the other actors or the people from Camp Rock 2,” she said.

“And it’s easy to excuse that behavior because I was so young and in so much pain, but I truly regret it and that’s a guilt that stays with you your whole life.”

Demi’s latest comments about her film come after JoJo Siwa, Drew Barrymore, Kenan Thompson and Raven-Symoné were announced as interview guests for Child Star.

It was also announced that the documentary will premiere on Hulu on September 17 and will be approximately an hour and a half long.

By the time Camp Rock aired, Demi, then 15, was already a star on the Disney Channel sitcom As The Bell Rings, which ran from 2007 to 2008.

As she grew older, she became a pop star, and her personal problems came increasingly into the spotlight.

Demi has spoken out about her past ‘experimentation’ with drugs, starting when she was a pre-teen after she had an accident and was prescribed opioids.

She stole her father’s beer and her mother’s Xanax, and at 17, she finally tried cocaine, she admitted in Call Her Daddy.

In 2018, she was hospitalized after a near-fatal heroin overdose, which left her with three strokes, a heart attack, and permanent brain damage.

Three years ago, she controversially described herself as “California sober,” meaning she still used cannabis but had later quit.

She has also been diagnosed with bipolar disorder and suffered from bulimia, binge eating disorder and purging, to the point where she vomited blood at one point.

Demi, who has come out as non-binary and prefers both the pronouns “they” and “them,” announced the Child Star documentary last year.
