Miley Cyrus: 19th Birthday Party Thrown By Kelly Osbourne!

Miley Cyrus celebrated her birthday inside the Beacher’s Madhouse club at Hollywood Roosevelt hotel on Tuesday (November 22).

Pal Kelly Osbourne threw the ultimate birthday bash for her celeb BFF, to which Miley tweeted: “Can’t thank @MissKellyO for the best partyyyy ever! =]]]] i loveeeee you! Let’s just say there was a unicorn in the lobby!” (A horse with a horn attached to its head was brought into the party.)

The blowout was attended by Miley‘s Aussie boyfriend Liam Hemsworth, dad Billy Ray, mom Tish, sister Brandi and pals Victoria Justice, AJ and Aly Michalka, and Justin Baldoni.

“Everyone went crazy when the mini Nicki Minaj impersonator performed ‘Super Bass‘” a partygoer tells JustJared.com.

Prior to the birthday bash, Kelly teased to E!, “It’s intimate, but it’s going to be the sickest [party] she’s ever seen in her life. Although I see her on the same level mentally as me, I also realize that Miley‘s 19 and she deserves to still have fun. Because that girl has so much pressure on her and has worked her ass off her entire life that I think a lot of the time people forget that she deserves to have fun too. So that was my mission for her, to make her birthday…the best day ever… I’ve got all sorts of madness and craziness.”

Also, below is Miley‘s latest video. “This is dedicated to the thousands of people who are standing up for what they believe in,” she wrote. Check it out!
