Justin Bieber raised eyebrows over the weekend after posting a series of intense messages on Instagram, cautioning an unnamed individual not to “mess with” him.

Among the posts was a photo of himself with his child, captioned with a raised middle finger emoji and a clear warning: he’s a father who should not be crossed.

The Grammy-winning artist also shared screenshots of a private conversation, showing a tense exchange where he expressed feeling invalidated and subsequently blocked the other party.

Speculation quickly mounted online, with many followers suggesting that the messages may be directed at longtime associate and former manager, Scooter Braun. The two have reportedly grown distant in recent years.

The posts have prompted concern from fans, some of whom are urging the pop star to seek emotional support or consider therapy in light of his increasingly candid — and sometimes alarming — social media activity.
