Just two weeks after pulling out of her appearance at the 2015 iHeartRadio Festival mere days before the show, Janet Jackson has also canceled two upcoming appearances on her Unbreakable World Tour.

According to the Associated Press, Jackson has been put on strict vocal rest and was forced to cancel both the October 9 and October 10 dates at the Planet Hollywood Resort and Casino in Las Vegas. She has moved the Las Vegas date to May 14, and it's set to take place at an arena that holds 20,000 people.

Live Nation Entertainment said ticket holders will receive a refund and will also get first dibs on tickets for the 2016 Las Vegas show. Tickets for the May 14th date will go on sale on October 16.

Although Jackson also canceled her appearance at the recent iHeartRadioFestival, it wasn’t due to her vocal cords. A rep told Billboard that she couldn’t get on a plane because of a health issue: “Due to a recent ear issue preventing her from flying, she is not able to perform at the Festival.”

As of right now, no other dates on the Unbreakable World Tour have been canceled. You can check out the remainder of shows below.
