(CNN) Justin Bieber is used to getting a lot of attention, but recently he appears to be attracting the kind Britney Spears got circa 2007.

That was the year that Spears volatile behavior led Spears' father and lawyer to take personal and financial conservatorships to control her and her estate. Bieber, 22, has been exhibiting some head scratching behavior as of late.

It started in late March when Bieber announced he would cancel meet and greets -- a decision which didn't sit well with those who had paid a premium to schmooze with Bieber before his concerts. Requesting a refund for the meet and greet meant also surrendering concert tickets.

"I'm going to be canceling my meet and greets," Bieber wrote in an Instagram post. "I enjoy meeting such incredible people but I end up feeling so drained and filled with so much of other people's spiritual energy that I end up so drained and unhappy. Want to make people smile and happy but not at my expense and I always leave feeling mentally and emotionally exhausted to the point of depression . "
