Zac Efron gets hand tattoo: What does 'YOLO' mean?

zac-efron-hand-tattoo-yolo.jpg Zac Efron got a new tattoo, ladies! At the Tokyo premiere of "New Year's Eve," the Disney-star-turned-actual-star debuted some fresh ink on the side of his hand: A simple black tat that says "YOLO."

Don't worry -- that's not the name of some exotic new girlfriend. According to TooFab, "YOLO" stands for "You only live once" -- Zefron's personal mantra.

It's not Zac's first tat; he's also got a feather inked on his bicep. Plus, if you're into dudes with tattoos, his upcoming film "The Lucky One" shows off plenty of artful fake tattoos in Zac's copious (and kind of gratuitous) shirtless scenes.

Zac may be jet-setting all over the world to promote his new movie, but he's still got time for his old Disney pals. He was there for his "High School Musical" co-star Ashley Tisdale while she was struggling through a sad breakup -- she even tweeted a picture of them with a note that says "So happy to have amazing friends in my life! #blessed"

We're just going to ignore the rose petal-covered bed behind them. Weird.
