Britney Spears was bitched out by a random passerby in Malibu this week -- and lil' sis Jamie Lynn stepped in to bitch her right back!
J. Lo almost took a dive after slipping during a concert in Connecticut. Those Jamiroquai moves can be tricky.


Haylie Duff's got a new boyfriend ... and surprisingly, people cared enough to make this the #3 video of the week.


It was fight night in Hollywood as yet another a bloodied up, drunk, wannabe brawler tried to break into fisticuffs in a club parking lot.


Britney Spears is "gorgeous" ... at least according to her.
