_That was apparently Miley Cyrus' anthem this year as she celebrated her 19th birthday a few days ago, thrown by good friend Kelly Osbourne at Beacher's Madhouse at the Hollywood Roosevelt Hotel. After partying hard, and singing along to all of her favorite birthday club jams, including "In Da Club" by 50 cent, she was presented with what seemed to have been her favorite present of the night-a Bob Marley birthday cake. She took to the mike, and seemed to have no will to dismiss smoking rumors, which looked to have gone lingering into the air. But then again, who could she blame? After all, who could forget the "bong" video that surfaced just last year at her 18th birthday.  Instead she commented, "This is amazing. You know you're a stoner when your friends make you a Bob Marley cake. You know you smoke way too much fucking weed!" I don't know about anyone else, but that sounds like a confession to me. And a proud one at that.  A rep spoke in her defense Monday "This is so ridiculous. The cake was a joke, and Miley was being sarcastic". Kelly Osbourne also ran to her friend's defense via twitter, tweeting "Let me make something very clear, after @mileycyrus Salvia we started calling her Bob Marley as a JOKE! The cake was also a JOKE! It makes me sick that @mileycyrus so called 'friends' would sell her out and lead people to believe 2 believe she is someone she is not!" As if she hadn't quite gotten her point across, Osbourne went back for more, later tweeting " U guys, if @mileycyrus is not recording/filming/touring she is works everyday how could she possibly do all that if she was a stoner!" Not one to judge but Osbourne sounded as if she was a little high on something herself when she tweeted that. Kelly, in case you didn't know, proof-reading is still cool, even if it is just a tweet. All in all, it looks like Miley has a serious problem with "Birthdays" and "Videos". The two just don't seem to mix in her favor. Little piece of advice Miley. Keep it private. You'll save yourself a hell of a lot of trouble. Posted by @tiffan700.
