The 'Boyfriend' hitmaker, who finally split from his on/off girlfriend earlier this month after two years being together, said he is not dealing with their split very well and is still heartbroken, reported Contactmusic.
"I'm not in the happiest place that I've ever been," he said.
Bieber, 18, tweeted a photo of his cover for a music magazine on with the caption "tried to be honest".
He is all set to release his new album 'Believe Acoustic' on January 29, which is said to include lots of songs about the couple's break-up.
