Justin Bieber posted on Instagram yesterday about all the rough stuff he's been going through lately.

At one point he even went as far as to bash Lindsay Lohan:

"And to those comparing me to Lindsay Lohan....Look at her 2012 tax statements"

He quickly deleted that part of the post however, it was seen by many and it's being reported that Lindsay knows about it.

She's not cool with it at all.

Bieber did kind of apologize for the post saying that he was getting off track of what he was trying to say. However, the damage was already done.

So, does this mean now that Lindsay and the Bieber are going to be feuding? That would be quite the hot mess.
