The musician shared the heartbreaking news to fans in an Instagram post on Thursday marking the end of his Forget Tomorrow World Tour – after sparking concern over his ‘tired’ stage performances and ‘lip syncing.’

What is Lyme disease?

Lyme disease is an infection caught from tick bites that causes muscle pain, brain fog, swollen joints and fatigue which can last for a few weeks, but for reasons not yet understood, some patients suffer for years.

Timberlake said in the post: ‘This has been the most fun, emotional, gratifying, physically demanding, and, at times, grueling experience.

‘I could not have done it without my family, friends, The TN Kids, and all of YOUR support.

What was Justin Timberlake diagnosed with?

‘Among other things, I’ve been battling some health issues, and was diagnosed with Lyme disease – which I don’t say so you feel bad for me – but to shed some light on what I’ve been up against behind the scenes.’

This comes days after the singer sparked concern among fans over his ‘tired’ appearance at one of his final tour concerts in Georgia last week.

He continued in full statement: ‘If you’ve experienced this disease or know someone who has – then you’re aware: living with this can be relentlessly debilitating, both mentally and physically. When I first got the diagnosis I was shocked for sure.

‘But, at least I could understand why I would be onstage and in a massive amount of nerve pain or, just feeling crazy fatigue or sickness.’

Timberlake said he initially considered canceling his year-long tour – but decided to ‘figure it out.’ 

‘I decided the joy that performing brings me far outweighs the fleeting stress my body was feeling. I’m so glad I kept going’ he wrote.

‘Not only did I prove my mental tenacity to myself but, I now have so many special moments with all of you that I will never forget. I was reluctant to talk about this because I was always raised to keep something like this to yourself. 

‘But I am trying to be more transparent about my struggles so that they aren’t misinterpreted. Sharing all of this with the hope that we can all find a way to be more connected. I’d like to do my part to help others experiencing this disease too.’

Timberlake cancelled his tour in Istanbul, Turkey on Wednesday, July 30.
