But he's also a real person with real feelings.
After admitting to being overwhelmed by anxiety, the Biebs put out a thoughtful message to his fans and followers.
Justin Bieber shared this black-and-white selfie on Instagram along with a lengthy, largely religious message.
"Don’t stop fighting the battle has already won," Justin begins.
He advises his fans and followers to "fight for what you love and who you love."
Justin then encourages them: "don’t let fear and anxiety win."
He is clearly speaking from personal experience.
Justin's heartfelt caption then takes a more explicitly religious tone.
He writes: "god has not given us a spirit of fear but of power love and of a sound mind!"
"I haven't believed the truth about myself," the Biebs laments.
"I haven’t believed I am loved," he admits. "I haven’t believed I am forgiven."
Justin confesses: "it’s a hard thing for me to wrap my head around."
"I hang my head in shame," Justin Bieber's emotional post continues.
"And," he writes. "I wallow in sadnes about the the people who have betrayed me."
Betrayed? That took one hell of a turn.
"Jesus has given me freedom," Justin expresses. "And the persuit of getting to know his character is never ending."
"Gods character never changes," he adds. "He is the same yesterday now and forever. He is always good!."
"I won’t be afraid to be vulnerable before him," Justin says. "His power is made strong in our weakness."
"God isn’t afraid of your pain and your brokenness," he writes. "He actually welcomes it."
"Come to me all who are weary and burdened and I will give you rest!" Justin quotes. "These are words from Jesus!"
"There is hope and it’s in him!!" he gushes. "He loves and cares for you!"
In addition to therapy and medication, a person can turn to spiritual practices or religious beliefs as an added comfort while battling any sort of mental illness.
"For god so loved the world that he gave his only son so that whoever believes him wont die but have eternal life!" Justin continues.
These comments should not come as a surprise to Justin's fans, who know that he is such a devout Christian that he canceled his tour a couple of years ago.
"You are that whoever and he accepts you as you are!!" he writes. "He loves and forgives you and welcomes you into his arms every time you mess."
Justin's caption concludes: "He is a perfect and loving god who adores you!"
That post might not mean much to some of Justin's fans, but to those who share his views, it could be very reassuring.
Either way, his fans are happy to see him express himself.
In addition to this powerful post, Justin shared a meme in which he and Ed Sheeran were presented as "crippled with anxiety."
Most people with anxiety disorders try to avoid using "crippled," out of respect for those with physical disabilities.
But anxiety can be intensely debilitating, even to people who otherwise seem to have everything going for them.
Mental illness can be just as cruel as physical ailments, but sometimes they are dismisses as "invisible illness."
If someone says that their anxiety is debilitating, they're not joking, and there's nothing weak or wrong about them.
When celebrities speak out about the ways in which they suffer, fans become more aware of how millions experience the world.
