How Hard Is It Being 19 in Hollywood?

From Justin Bieber's recent birthday blues to Drew Barrymore's blink-and-you-missed-it marriage, see who ended their teenage years with a bang … or a bong

MILEY CYRUS

She's a singer, an actress ... and a midnight toker? While kicking off her 19th birthday in 2011 at a Hollywood bash thrown by Kelly Osbourne, Cyrus was treated to a cake made in tribute to reggae legend and pot advocate Bob Marley. "You know you're a stoner when your friends make you a 'Bob Miley' cake. You know you smoke way too much f–cking weed," she said in a video taken at the private party. A rep for the starlet later called the incident a joke, saying, "Miley was being sarcastic."
