Justin Bieber’s latest social media posts have his fans raising red flags — with many urging the pop star to seek help as concerns over his mental health continue to grow.

The singer shared a carousel of selfies in the bathroom on Saturday on Instagram, posing in the mirror with exaggerated facial expressions and a cryptic caption that read, “U could point at my flaws Or u could recognize ur own lil b****.”

While JB may have meant it as a tongue-in-cheek jab, fans weren’t laughing. One wrote, “He’s clearly not okay.” Another wrote, “Why are the people around him not helping?”

One even compared Bieber’s unraveling public image to that of Britney Spears, writing, “He’s slowly turning into the Britney of our generation.”

We broke the story … Biebers rep told us in February the recurring narrative that Justin is using hard drugs is absolutely not true. The rep said JB is in one of the best places in his life … actively parenting his newborn son with Hailey and working on new music.
