Beyoncé fans, brace yourselves for disappointment. The “Sorry” singer has been forced to postpone her scheduled stop at MetLife Stadium in East Rutherford, New Jersey, due to medical issues.

According to a report from Complex, a doctor has ordered Beyoncé to spend the next few days on “vocal rest.” It remains unclear what the exact issue is or how long the 10-time Grammy award winner will be restricted from performing. The show, which was scheduled for Wednesday, September 7, has been rescheduled. Fans who previously purchased tickets to the show will be able to use those tickets on it’s new date, October 7.  Refunds will also be available to those unable or unwilling to attend the new date. It is not believed that the schedule change will affect upcoming shows in St. Louis; Los Angeles; Santa Clara, California; Houston; New Orleans; Atlanta; Philadelphia or Nashville. An apology has been issued by both Live Nation and Parkwood Entertainment.

Beyoncé may be resting her vocal chords, but she didn’t let her ailment keep her from getting down on her 35th birthday. According to Us Weekly, Beyoncé, Jay Z and several of their closest — and most famous — friends gathered at the NoMad Hotel in New York City on Monday for a “Soul Train” themed shindig. The birthday girl was seen sporting a yellow bodysuit, gold platform pumps, flashy shades and a matching gold duster coat as she entered the venue. She made her entrance with husband Jay Z in tow sporting a paisley shirt, three gold chains and black suede boots. Notably missing was the afro wig he wore to complete the look once inside the venue. Former Destiny’s Child members Kelly Rowland and Michelle Williams were also in attendance and stepped out dressed to the nines in theme-appropriate attire. Chance the Rapper, Kendrick Lamar, Solange Knowles, Sean “Diddy” Combs, Alicia Keys, Chanel Iman and more were also said to have been in attendance.

News of Beyoncé’s vocal issues comes just under two weeks after she brought down the house during the 2016 MTV Video Music Awards. There was certainly no sign of vocal distress during her performance, which spanned 15 minutes or more of the show’s airtime. In addition to wowing the crowd with live performances of songs off her “Lemonade” visual album, Beyonce took home several awards during the show. The mother of one won awards for Best Choreography, Video of the Year, Bed Direction, Best Pop Video, Best Cinematography and Best Long Form Video. All of the aforementioned awards were for “Lemonade,” according to The Hollywood Reporter.
