Between her performance in Rock Mafia's "The Big Bang" music video and filming of movies So Undercover and LOL, Miley Cyrus has had quite a year -- and she's celebrating her birthday with the help of pal Kelly Osbourne, who planned her party. "It's intimate, but it's going to be the sickest thing she's ever seen in her life," Kelly says. "Miley's 19, and she deserves to have fun. My mission is to make her birthday the best day ever." Join J-14 in wishing Miley a very happy 19th birthday!
