Justin Bieber finds love "exhausting".

The 'Peaches' singer - who has eight-month-old son Jack with wife Hailey Bieber - feels love is something he needs to "earn" and he doesn't always find the effort easy.

He wrote on his Instagram Story: "Love isn't a u get what u put in kinda thing.

"It's a receiving thing. Still find myself trying to earn love. And It's exhausting."

Justin, 31, noted he is loved "no matter what" he does but still struggles to think love is "deserved".

He continued: "People telling me I deserved things.

"Made me exhausted from trying to prove I was worthy at times.

"Also made me feel more entitled at times.

"It either makes us feel not good enough or that we're owed something. True love is freely given with no expectation.(sic)"

Justin has shared a number of similar candid posts over recent months amid speculation about his physical and mental health.

He recently declared he is keen to tackle his "anger issues" and "grow" as a person.

He wrote: "I got anger issues too, but I wanna grow and not react so much smh.(sic)"

A few hours later, the 'Baby' hitmaker admitted he "hates" himself some times and thinks it is important to be authentic and not try to change to "please people".

He wrote alongside a video of him jamming with a group of musicians: "I think I hate myself sometimes when I feel myself start to become inauthentic.

"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."

And shortly before then, the 'Love Yourself' singer told of how he struggled to express "hate" and was left feeling "unsafe" as a result.

He shared a message on his Instagram Story which read: "I was always told when I was a kid not to hate. But it made me feel like I wasn't allowed to have it and so I didn't tell anyone I've had it.

"Which made me feel like I have been drowning feeling unsafe to acknowledge it. I think we can only let hate go by first acknowledging it's there. How couldn't we feel hate from all of the hurt we have experienced?(sic)"

Justin also recently told fans he felt like a "fraud" and had struggled with imposter syndrome.

He wrote on Instagram: "People told me my whole life, 'Wow, Justin, you 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 they only knew my thoughts. How judgmental I am, how selfish I really am... they wouldn't be saying this.

"I say all this to say, if you feel sneaky, welcome to the club. I definitely feel unequipped and unqualified most days."

exhausting and pitiful and shows that despite the obvious truth, people are committed to keeping negative, salacious, harmful narratives alive."
