Justin Bieber was once seen as one of the most handsome young artists in the world. But he's been plagued with stress, drug use, and mental health struggles - and it's affected his looks.

Justin released a new fan pic, and many on social media were shocked at how different he looks now.

Here's the pic showing Justin's new look:

Here are some of the comments from Twitter:

Lord knows Justin looks like Tobias Funke from Arrested Development.

 He looks like he should be in his front yard working on his car.

Justin is one of the biggest artists in pop music. His album and singles sales total 44.7 million. He has sold an estimated 150 million records, making him one of the world's best-selling music artists, and became the second person to reach 100 million followers on Twitter in August 2017 after Katy Perry.

Bieber has won numerous awards throughout his career, including an American Music Award for Artist of the Year in 2010 and 2012, a Grammy Award for Best Dance Recording for the song "Where Are Ü Now", and a Latin Grammy Award.

He has been listed three times by Forbes magazine among the top ten most powerful celebrities in the world, in 2011, 2012, and 2013. In 2016, Bieber became the first artist to surpass 10 billion total video views on Vevo.

Justin's wife Haley Baldwin, 22, opened up to Cosmopolitan recently about social media after her pop star husband told fans earlier this month that he’s been “struggling a lot lately.” His comments came following reports he’d undergone treatment for depression.

"The problem too is kids become possessive over people and feel like if they think they’re hurt, they feel hurt for them and they’re hurt too, or whatever it is. They just think they know these people who are famous because their life is so exposed. And that’s what gets me, I think, the most frustrated," Baldwin told Cosmopolitan.
