Ariana Grande Sidelined by Vocal Cord Hemorrhage

Within hours of finding out that her debut album, "Yours Truly," was going straight to number one, doctors ordered Ariana Grande to stop using her voice immediately.

ABC News has confirmed that the 20-year-old singer, whose wide vocal range has drawn comparisons to superstar singer Mariah Carey and the late Whitney Houston, had suffered a vocal cord hemorrhage.

"For those of u asking about my voice I screamed too much at my party totally irresponsible but it's better now, thanks for the well wishes," the 20-year-old pop star Tweeted Wednesday night.

According to Dr. Jennifer Long of the UCLA Medical Center, a vocal cord hemorrhage occurs when a blood vessel within the vocal cord ruptures, causing a bruise in the delicate tissue used to produce voice. Long, who has not treated Grande, said the injury could permanently change voice quality of it's not treated appropriately.

The injury has forced Grande to cancel dozens of media appearances designed to capitalize on her chart-topping hit, "The Way."

Actress Ariana Grande chats about her role as "Cat."

Only 15 other female vocalists have made it to number one on the charts with a debut album, among them Britney Spears, Beyonce and Alicia Keys.

Grande's rising star status landed her a performance before her peers at the MTV Video Music Awards last month.

Christina Garibaldi, a producer/reporter for MTV News, said Grande made an impact. "The reaction at the VMAs, was like 'wow, who is this girl? I need to hear everything she's even done' … the momentum helped push her album to number one," Garibaldi said.

Celebrity Voices Saved by Surgery

Grande may have been a relative unknown in the music world until now, but she's already a big hit in the world of children's television as the co-star of Nickelodeon's "Sam and Cat."

It's her singing, though, that expected to catapult her to superstardom.

"She's has this incredible range, like Mariah Carey, like eight octaves, she's worked with Babyface, who hasn't done anything in years, she has [Justin] Bieber's manager, she's in good hands," Garibaldi said.

Grande is promising fans she'll be back soon.

In a message to her nearly 9.5 million Twitter followers, Grande wrote: "Thank you guys for the well wishes, I'll be better in no time … just need some rest."
