Ariana Grande Hemorrhages Vocal Cords

Ariana Grande's career is just taking off with comparisons to Mariah Carey and others, but the pop star's future could be in jeopardy. INSIDE EDITION has the scoop.

Ariana Grande may be the hottest singer out there today.

She just appeared on the VMAs, and she performed a live concert on the Today show. Her debut album just hit No. 1 on the Billboard charts. People are even comparing her voice to Mariah Carey and Whitney Houston.

But today, Grande's voice is silenced. Just hours after hitting No. 1, she suffered a potentially career-ending hemorrhage of her vocal cords.

Dr. Michelle Yagoda said, "that hemorrhage can happen right away from trauma, the vocal cords can hit against each other which causes it, and if they continue to use their voice while it's there, they can develop nodules or polyps."

It's not yet known what treatment the 20-year-old star of TV's Nickelodean will have to undergo.

She's trying to reassure her fans with this  tweet: "for those of u asking about my voice i screamed too much at my party totally irresponsible."

"It's extremely important for Ariana to follow the doctor's order because it can be the difference between a long-term career and one that ends abruptly," said Dr. Yagoda.

The same medical condition silenced superstar, Adele in 2011. She underwent surgery and was sidelined for months. There was even a concern the procedure could alter her magical voice. Luckily the operation was a success.

As for Ariana Grande, time will tell if her powerhouse voice will recover.
