Justin Bieber posted an angry rant including a nasty slam on Lindsay Lohan ... but then tried to take it back. Why's JB lashing out -- and more importantly, why throw LiLo under the bus?? Plus, Charlie Sheen's also going off ... on his daughter's school! Charlie thinks his little girl was bullied, and now he's taking it out on the school with a crappy call to arms. Is that fair? And, Jennifer Lawrence is so likable ... not even hate groups hate her.
