Singer Demi Lovato, who grew up in Grapevine, has been hospitalized in California after she suffered what appeared to be an overdose on heroin, according to multiple media outlets.
The LAPD confirmed to People.com that authorities "responded to a medical emergency at the 8000 block of Laurel View Dr. at 11:40 a.m" and the Los Angeles Fire Department said they transported a 25-year-old female patient to the hospital.
Last month the singer dropped her new song, "Sober," that revealed she had relapsed after six years of sobriety.
“Mama, I’m so sorry I’m not sober anymore. And daddy please forgive me for the drinks spilled on the floor,” Lovato sang. “To the ones who never left me, we’ve been down this road before. I’m so sorry, I’m not sober anymore.”
"I wanna be a role model, but I’m only human,” she sang a few songs later.
The 25-year-old pop star has spent years battling substance abuse, disordered eating and her diagnosed bipolar disorder in the public eye. Her 2017 documentary "Simply Complicated" followed the singer as she navigated sobriety, revealing the extent of Lovato's drug use at the height of her Disney Channel fame when she was a teenager.
Lovato, who was a regular on "Barney & Friends" filmed in North Texas, attended Grapevine High School and Cross Timbers Middle School, where she shot her music video for the hit song "Waitin For You."
As Tuesday's news spread, fellow artists, including Ariana Grande, shared their support on social media.
Brad Paisley said he was praying for his "brave" and "honest" friend, calling addiction "a terrifying disease."
Ellen DeGeneres said the news broke her heart.
"I love @DDLovato so much. It breaks my heart that she is going through this. She is a light in this world, and I am sending my love to her and her family," she tweeted.
According to Entertainment Tonight, her last appearance was Sunday at the California Mid-State Fair, where she performed alongside Iggy Azalea.
Lovato was scheduled to perform Thursday in Atlantic City, New Jersey.
