Justin Bieber has once again given his social media followers insight into his mental health struggles.

Taking to Instagram on Saturday, the 31-year-old singer shared a long video of a jam session with musicians, including DJ Tay James and Judah Smith.

He wrote in the caption, 'I think I hate myself sometimes when I feel myself start to become inauthentic.'

The father-of-one, who shares seven-month-old son Jack with wife Hailey Bieber, added, 'Then I remember we’re all being made to think we’re not enough but I still hate when I change myself to please people.' 

It comes shortly after he admitted to having 'anger issues' in another online post.

Saturday's post saw the Canadian crooner in a yellow beanie hat, black jacket, and light-colored pants as he banged away on a keyboard.

Despite his self-critical caption, he generally appeared upbeat in the footage, losing himself in the music.

He went on to share a post from fellow music artist Jensen McRae, in which he flashed his megawatt smile in a sun-drenched selfie.

Earlier in March the former teen star wrote in a message shared on the internet, 'People told me my whole life 'wow Justin u deserve that' and I personally have always felt unworthy. 

'Like I was a fraud, Like when people told me I deserve something, it made me feel sneaky like, damn if only they knew my thoughts. How judgmental I am, how selfish I really am, they wouldn't be saying this,' he added.

The Honest hitmaker concluded, 'I say all this to say. If you feel sneaky welcome to the club. I definitely feel unequipped and unqualified most days.'

Before that, days earlier, he advised his fans, 'We have nothing to prove today. Nothing is owed to us and we [don’t] owe anyone anything ♥️.'

Paparazzi images of the entertainer looking unusually tired and disheveled earlier this year sparked online speculation that he could be using drugs. 

But a rep for the Yummy artist told TMZ in February, 'The recurring narrative that Justin is using hard drugs is absolutely not true.'  

It was added that the new dad is 'in one of the best places in his life.'  

He celebrated his March 1 birthday with wife Hailey by his side as she appeared in the singer's birthday posts on Instagram, showing that despite swirling rumors, their six-year marriage is intact.

The pop star even gave fans a glimpse at their baby boy, whose face they have kept private.
