It's lonely at the top!
You might think that the beautiful, rich, and famous Kate Upton has quite the life, but she's not immune to criticism!
Well, actually she's been criticized quite a few times, but this particular occasion was especially harsh considering she was booed right to her face! So rude!
Apparently, fans (and probably paps) were annoyed that she didn't stop to sign autographs at the premiere of The Other Woman last night in El Lay.
One jerk even called her a name we'd rather not type!
Check out the rudeness ...AFTER THE JUMP!!!
