Disney starlet Miley Cyrus celebrated her 19th birthday in style last night with the help of close friend Kelly Osbourne. 

Planning of the exciting event was spearheaded by Osbourne, who promised she would make her friend's celebration "one to remember" and according to Cyrus' Twitter feed it seems as though she kept her word.

The singer and actress attended a party at Beacher's Madhouse inside the Hollywood Roosevelt Hotel on November 23 that was thrown by Osbourne, and wrote a message to her Twitter followers that explained the bash included a unicorn:

"Can't thank @MissKellyO for the best partyyyy ever! =]]]] i loveeeee you! Let's just say there was a unicorn in the lobby!"
