Adam Levine isn't the first or the last celeb to stir up a frenzy among fans by baring it all -- but he certainly does do it with some frequency. Between his Instagram, his music videos and his live performances, the Maroon 5 frontman seizes just about every opportunity to show off his yoga-toned body. As the singer turns 36 on March 18, we look at some of his best (and most provocative) shirtless moments. Here's hoping none of his birthday presents are shirts!
Prior to appearing at the 2015 Oscars, Levine posted a photo of one of his potential red-carpet looks. He may have ended up wearing a shirt to the event, but at least on Instagram he was able to show his true colors.

The only requirement of Levine's 2007 Halloween costume is that it fits the theme of "shirtless" -- thus, Brad Pitt's character in Fight Club was an ideal choice.
