LOS ANGELES: Even Beyoncé needs to slow down every once in a while. Under doctor's orders for vocal rest, the superstar singer has postponed the September 7 MetLife Stadium stop of her Formation World Tour until October 7, according to a statement released Monday.

Fans in St. Louis, Los Angeles, Santa Clara, Houston, New Orleans, Atlanta, Philadelphia and Nashville can rest easy though. Queen Bey will be proceeding with those dates as planned.

The Formation World Tour in support of her album "Lemonade" kicked off April 27 in Miami and was to conclude October 2 in Nashville.

Beyoncé turned 35 on Sunday and attended the Made in America Festival in Philadelphia with her husband and festival founder Jay-Z.

MetLife Stadium is in East Rutherford, New Jersey.
