Fans of Lady Gaga were devastated last night when the pop icon was forced to cancel a concert due to poor health.

20 minutes before she was to appear on stage at the Park Theater at the Park MGM Casino, the venue announced to waiting fans the show was canceled.

Gaga, 33, posted a photo to her social media showing herself hooked up to an IV drip, accompanied by a message which said, “I’m so devastated I can’t perform tonight for so many people who traveled to come see me.

“I have a sinus infection and bronchitis and feel very sick and sad I never want to let you down.

“I’m just to [sic] weak and ill too [sic] perform tonight. I love you little monsters I’ll make it up to you. I promise.”

The tweet has had received over 90k likes and thousands of comments. Most of the latter have been supportive, with fans telling Gaga to take care of her health and wishing her well. Others, however, have been less positive, with one poster responding, “[T]his comes after she cancelled 3 more of my shows last year – so far none of those have been “made up to me” as promised either. Yes I want her to get better. No she shouldn’t have performed. I’m still allowed to be angry.”

Gaga’s  performance schedule has been impacted by health problems before. In 2017, she postponed some dates on her European tour and revealed that she lived with the chronic pain condition, Fibromyalgia.

Last night’s scheduled show was part of the singer’s current Enigma residency at the MGM Grand. She has two more performances left on the third leg of her residency (November 8-9), and then a fourth leg at the end of December. The fifth and final leg runs from April 30 to May 16, 2020.

The concerts are divided into separate Enigma shows and Jazz & Piano shows, showcasing different sides to her artistic output. The Jazz shows featured stripped-down versions of her hits and American songbook classics.

The MGM Grand tweeted news of the cancellation, saying, “With her deepest regrets, @ladygaga announces the cancelation of tonight’s performance at Park MGM because she is suffering from a sinus infection and bronchitis. She plans to return to the stage for her scheduled show on Friday, Nov. 8.”

Some fans expressed concern that the singer has been pushing herself too hard – in addition to her concerts, she’s recently been signed for her first major film role following the success of “A Star Is Born” and has been busy in the studio working on her sixth album.

Gaga has joked that the album will be titled, “Adele.”
