Miley Cyrus celebrated her 19th birthday in style with a lavish private party at the nightclub Beacher’s Madhouse inside the Roosevelt Hotel in Hollywood, according to Us Weekly.


“Her mom, Tish, went and so did her boyfriend, Liam [Hemsworth],” a source says of the party, which was put together by pal Kelly Osbourne.


“The group was up until 3 a.m. just dancing up a storm and having fun.”


Cyrus definitely seemed pleased, calling the event “the best party ever” on Twitter.


“Let's just say there was a unicorn in the lobby,” she tweeted.


And according to E! News, there was in fact a horse with a horn attached to its head inside the party.
