Miley Cyrus Engaged 2012: Parties Hard Sans Engagement Ring and Liam Hemsworth

Looks like Miley Cyrus' new style and funky haircut have influenced some hard-partying ways over the past few weeks. According to a recent post on perezhilton.com, Cyrus was spotted at a Philadelphia recording studio, smoking marijuana and supposedly whining about fiancé Liam Hemsworth (coincidentally, during a recent drunken stupor Cyrus was also seen rummaging through her purse to try and find her misplaced engagement ring).

While the "Party in the USA" singer's hubby was off at work filming the upcoming film "Paranoia," Cyrus was allegedly heavily partying and flirting with a few guys at a Philly recording studio. Rumors have it that Cyrus was willing to share her weed amongst the party crew freely, and was getting pretty buddy-buddy with one intern.

The highlight of this "alleged" night of bad decision-making: the "Last Song" star said, according to one source, "Yeah, I'm engaged, but who knows how long that will last."

The same inside source claims that at one point during a drunken night out, Miley was spotted digging through her purse, laughing about how she couldn't find her diamond engagement ring bling.

Maybe Cyrus is just letting loose before she really has to buckle down with fiancé Hemsworth? The couple do plan on moving in together (reportedly to Cyrus' San Fernando Valley childhood home) so things can't be that bad, right?
