Miley's B-day -- Spit for Tat

Miley Cyrus officially turned 16 yesterday, even though she's been celebrating it for ... about a year.

And there were untold levels of Freudian complexity over the b-day weekend, according to Perez Hilton, who reports Miley, BF Justin Gaston, and dad Billy Ray Cyrus went to tattoo parlor on Friday night. It was papa C who got inked up, while Miley and Justin swapped saliva during the tatting-up.
