Canadian pop singer Justin Bieber has revealed he has been diagnosed with Lyme disease.
"It's been a rough couple years," the 25-year-old wrote on Instagram, adding that he was also suffering from a chronic viral infection.
The star said he was aware of social media speculation that he had a drug problem, after he was pictured looking unwell with blotches on his skin.
Lyme disease is a bacterial infection caused by ticks, reports the BBC.
The symptoms often include a rash, muscle pain, and tiredness.

On his Instagram page, the artist wrote that people had suggested he looked like he was "on meth", but "they failed to realise I've been recently diagnosed with Lyme disease, not only that but had a serious case of chronic mono which affected my skin, brain function, energy, and overall health".
