Adam Levine -- Shirtless & Tatted Up in Hawaii

A beefier and hairier Adam Levine showed off his still buff and inked up moves like Jagger while in Hawaii the other day.

The scruffy 33-year-old enjoyed some down time from getting along, er, splendidly with his fellow "The Voice" judge Christina Aguilera to bask in the warm sun of Kauai.

Being quite the ladies man, you can bet the Maroon 5 singer got lei'd.
