Justin Timberlake postponed his Wednesday night concert in New York City because his vocal chords are “severely bruised.”

The pop star wrote on Instagram that under doctor’s orders he had to postpone his show at Madison Square Garden. He performed at the famed venue on Monday night.

Timberlake says he has rescheduled the MSG concert for January 31, which is his 38th birthday. He writes, “I’m going to make this up to you.”
