Ariana, whose album Yours Truly debuted at number 1 on the Billboard 200, has been working the talk show circuit and a variety of other appearances--no doubt it's all taken a toll.
She's had to cancel some upcoming performances, according to a Page Six report, with a source noting, "Ariana had a show in LA on Monday night, then on Tuesday she woke up and felt unwell. She tried to sing with her vocal coach, who recommended she see a doctor."
The insider added, "She has a vocal cord hemorrhage. She is devastated at this news, but she knows she will have to rest."
Ariana told fans on Twitter: "My 1st album has debuted at #1 & I can't even begin to express my gratitude. Thank you for supporting my music, this really means the world."
Ariana is the first female artist to debut at Number 1 with her first album since January 2010.
Rest and feel better soon, Ariana!
UPDATE: Ariana tweeted about her vocal rest and thanked fans, writing: "First day off in forever... Vocal rest and watching movies in with my best friend @alexaluria dunno what I'd do without her."
She added: "Thank you guys for the well wishes, I'll be better in no time.. just need some rest"
Ariana also updated curious fans about how the vocal cord injury happened, tweeting: "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"
