American singer, Ariana Grande has canceled a Las Vegas concert due to “health issues,” the singer said.

The 25-year-old singer, one of the most popular in the United States, was set to perform at The Cosmopolitan hotel today - her first full performance since both the death of ex-boyfriend Mac Miller and her breakup with Saturday Night Live‘s Pete Davidson.

She took to her instagram page earlier to confirm the cancellation: "Vegas, I'm currently working through some health issues and am beyond sorry I won't be able to see you this weekend. I love you and so look forward to seeing u and making it up to u next year."

Entertainment website TMZ reported that Grande had bronchitis, citing sources close to the singer. A representative for Grande was not immediately available for comment.

Grande finished 2018 with her song “Thank U, Next” at the top of the Billboard Hot 100 chart for the sixth week.

It has been a challenging year for the talented artiste which also saw the death of ex-boyfriend and rapper Mac Miller in September and her break up with fiancé Pete Davidson in October.
