Celebrating her 18th birthday, Miley was spotted out and about in Studio City, California last night (November 23).
She was reportedly joined by her on-again-off-again boyfriend Liam Hemsworth (not pictured).
The source also says Taylor Swift tweeted her "Happy Birthday Miley. Your 18 [sic]. Not 21. Just remember that. :-)" but it was actually a fake twitter.
