This brought tears to our eyes!!
Next to a photo of the letter, Miz King penned:
After the 19-year-old tweeted the picture (above) on Tuesday, she reportedly downed shots of Patron and partied at the Electric Room until the wee hours of the morning.
Most underage bar patrons try to keep their presence low key to avoid getting found out, but not Mileybird! The former Hannah Montana star proudly danced on couches in a VIP bottle service area of the 21 and up club.
Since she is no stranger to this kind of behavior, we're sure Liam will get another opportunity to see the love of his life mix it up with the fairer sex in the future.
Still though, it's a well-known fact that Miley is NOT of drinking age. Obvi, we know the club welcomed her inside because of her celebrity status, but that doesn't make it legal!
Check yourself, Miss Miley! Don't be going too crazy now!
