But MILEY CYRUS is already well on her way - with TWO boyfriends at the tender age of 17. The Hannah Montana star says she's spoilt for choice dating Aussie hunk LIAM HEMSWORTH - and pint-sized singer JUSTIN BIEBER. Miley quipped: "I have my travel-size boyfriend and I have my oversized security boyfriend. It's perfect!"
The teen sensation should be careful what she says if she wants to avoid bust-ups with the Bieber Fever brigade. KIM KARDSASHIAN revealed she was threatened by Justin fans after posing with him for a pic. Miley met Liam, 20, in 2009 while filming The Last Song together. The former Neighbours actor reportedly ended his relationship of five years to be with Miley.
