Singer Justin Bieber has revealed he has Lyme disease.

The confession came during his YouTube documentary, which comes out January 27.

While many Beliebers thought Bieber was spiraling down due to depression, it was the scary symptoms he had to endure instead.

According to TMZ, Bieber was diagnosed with Lyme disease late in 2018. It’s still unknown how he contracted the disease, which comes from a tick bite.

This explains why Bieber kept delaying the release of his new song.
