Miley Cyrus may think she is a big girl at the age of 17 but unfortch for her, that is not the case. It is being reported that Miley and her posse tried to roll up on a 21 and over nightclub called Club LIV inside The Fontainebleau Hotel in Miami Beach, FL on Wednesday night but due to the fact that she is REALLY underage, she was turned away and was NOT let into the club. My guess is that the embarrassing denial really upset young Miss Miley cuz she was lookin’ pretty pissy when she checked out of the hotel the next day:

Miley Cyrus doesn’t hear the word “no” very often — but TMZ has learned that’s exactly what she heard when she tried to get into a club in Miami Beach Wednesday night. We spoke to multiple people connected to the 21-and-over Club LIV at the Fontainebleau hotel — including a manager, an owner and a rep — who all told us Miley and her posse showed up to party at the hotspot like they were adults. They all told us Miley was turned away at the door because she obviously didn’t meet the age requirement … despite the fact that she has the voice of an 81-year-old chain smoker. Miley’s rep tells us this didn’t happen … even though it wouldn’t be the 17-year-old singer’s first time at a bar.

LOL. Poor Miley … so eager to grow up. I really hope that she wasn’t wearing this Jonas Brothers t-shirt when she was trying to get into the nightclub cuz, hello, that would be a big giveaway that she is still a child. At least she can be happy that she managed to find a tattoo parlor willing to ink her 17-year old bod (even tho my guess is that you have to be 18 to get tattooed). I guess even Miley Cyrus needs to learn that sometimes you win some and sometimes you lose some.
