Janelle Monáe has joined a growing list of high-profile acts to cancel tour dates in recent weeks, having announced Tuesday that she will be unable to perform tonight's Anaheim date in addition to others.

In a letter to fans, the singer explained that she's received "doctor's orders for mandatory vocal rest," forcing her to withdraw from Tuesday's performance as well as shows in San Diego and Phoenix later this week. At press time, her Nov. 9 date in Dallas was still on the docket.

Her full letter is below.

To all my fandroids, electric ladies, supporters and jam lovers:

Starting today, I am under strict doctor's orders for mandatory vocal rest. Not doing so could possibly result in damage to my vocal cords.

Unfortunately, this diagnosis means I will have to postpone my coming concerts in Anaheim, San Diego and Phoenix, a fact which truly leaves me heartsick and shaken because I live for this: connecting with you and giving you a one of a kind concert experience.

But alas, apparently even the most expertly designed android breaks down sometimes and must recharge...

I promise to see you sooner than you think my friends, stronger than ever.

I love you all dearly.

My sincerest apologies.

Best,
Jane
