Miley Cyrus may be shooting for a more grown-up image lately, but it sounds like she got in touch with her inner child at her 19th birthday party! Planned by Miley’s So Undercover co-star Kelly Osbourne, the soiree went down Nov. 23 at Hollywood’s Roosevelt Hotel, Us Weekly reports, and lasted until around 3 a.m. The guest list boasted big names like Liam Hemsworth, Victoria Justice – and a unicorn!

That’s right, a unicorn. We’re officially jealous.

Also celebrating Miley’s big 1-9, according to E! Online, were parents Billy Ray and Tish Cyrus; sisterBrandi Cyrus; pals Aly and AJ Michalka; and of course, the party planner herself, Kelly Osbourne.

And it sounds like Miley had a great time, taking to Twitter to express her gratitude for the festivities.

“Can’t thank @MissKellyO for the best partyyyy ever!” she tweeted in the wee hours of Nov. 24. “I loveeeee you! Let’s just say there was a unicorn in the lobby!”
