New Kids on the Block singer Jonathan Knight revealed that he suffered an injury on the group’s tour bus Sunday.

NKOTB, TLC and Nelly are performing around the country in support of their Main Event tour, which is scheduled to roll into San Diego, Calif., on Monday and Glendale, AZ on Tuesday.

The 46-year-old followed up the initial tweet with a gory selfie showing his bruised cheek, busted lip and bloody nose.
