Watch: Justin Timberlake conducts silent interview with Jimmy Fallon after bruising vocal chords

Justin Timberlake conducted an entirely silent interview with Jimmy Fallon on "The Tonight Show" last night.

The music superstar has bruised his vocal cords, and was forced to postpone a gig at Madison Square Garden last week.

Bruising of the vocal cords can be caused by overuse of the voice, though Timberlake joked that he had bruised them while fighting a bear on a mountain, or during a shark attack.

The 37-year-old has been performing on his "Man of the Woods" tour, but is now on vocal rest, and he joked that his wife, Jessica Biel, loves the silence.

The star was appearing on "The Tonight Show" to promote his book, "Hindsight: and All the Things I Can't See in Front of Me." In it, Timberlake shares behind the scenes stories, rare photos and personal reflections on his career, his wife and their son, Silas.

Timberlake's Madison Square Garden show has been rescheduled for January 31 2019, his 38th birthday.
