Seth Rogen Weighs in on “Obnoxious, Ungrateful” Justin Bieber

While our neighbors to the north are usually pretty peaceful, there’s definitely animosity brewing between Canadians Seth Rogen and Justin Bieber.

During his interview on “Watch What Happens Live,” the “Knocked Up” hunk gave his unfiltered opinion of the “All That Matters” singer.

Rogen began, “Justin Bieber is a piece of sh*t. He’s obnoxious, he’s ungrateful, he’s insincere. He puts people’s lives in danger.”

Once Bieber finishes with all of his legal problems, we’re sure he’ll issue a response to Seth’s remarks, and it could get pretty heated if Justin’s temper tantrum at last week’s deposition is any indication.
