For Mother's Day, Justin Bieber took his mom to the Thunder/Clippers playoff game at Staples Center yesterday afternoon and sat courtside with her. Pretty nice, right? Uh, yeah. But don't tell that to Clippers fans.

Despite the nice gesture, the Clips crowd was not amused when Biebs made an appearance on the JumboTron during the game. So they booed Biebs. And then booed him some more. And then booed him some more, just to let him know that they didn't like seeing him at the game.

Maybe they don't like his music. Maybe they don't like his recent antics. Or, better yet, maybe they remember this:

Yeah, that must be it. Boooooooooooooooooooo!
