Celine Dion announced on Wednesday she is canceling her Las Vegas shows to undergo a surgical procedure for an ear condition.

The 49-year-old singer said in a Facebook post she has been dealing with an ear condition called Patulous Eustachian tube. The condition is causing hearing irregularities that she said have been impacting her singing.

Dion has been dealing with the condition for 12 to 18 months and treating it with various ear drop medications. However, the medication recently stopped working, she wrote.

“During the past couple of weeks these medications have no longer been working to treat the condition, so she will undergo a minimally invasive surgical procedure to correct the problem,” the post read.

“My luck hasn’t been very good lately... I’ve been so looking forward to doing my shows again and this happens… I just can’t believe it! I apologize to everyone who planned to travel to Las Vegas to see my show. I know how disappointing this is, and I’m so sorry," Dion said.

Dion is expected to resume shows at Caesars Palace's The Colosseum on May 22. Tickets for the canceled dates will be refunded.

This isn’t the first time The Grammy-winning singer had to cancel shows due to health issues. Dion was forced to nix seven concerts in January due to congestion and irritation of the vocal chords. The shows were expected to resume on March 27 before her latest health issues were announced.
