Whether you're out on the town or just at home watching a DVD, a BFF makes everything more fun. Take it from Hollywood -- where trivial gossip makes front page news -- a good friend is hard to come by. And in a world where mean girls can always target you online, it doesn't matter if you're a big-time teen celeb or an average high school student. That said, it's always good to have a true pal who stays by your side even when the going gets tough. Just ask celeb BFFs Miley Cyrus and Kelly Osbourne: after Miley's recent negative press, Kelly showed the true meaning of friendship when she took to her twitter to set the record straight for Miley. She wrote: "Let me make something very clear after @MileyCyrus salvia incident we started calling her bob miley as a JOKE!"
When critics responded to Kelly, Miley then took to her twitter: "Please stop bombarding my friends twitter pages with rude comments. NOTHING gives you the right to threaten people. I love u @MissKellyO :)"
Kelly's response? "@MileyCyrus i love you more!!!!!!! thanx for having my back you know i ALWAYS have yours! xoxoxoxox"
In honor of Miley and Kelly's adorable twitter devotion to each other, here's a list of our fave 10 young celeb BFFs. Which is most like you and your best friend?
