Twenty-five days of Christmas? More like 25 days of HOTNESS.

Since we love this time of year just as much as Mariah Carey does, we're giving you a gift every single day leading up to the jolly holiday…in the form of 25 hot dudes in Hollywood.

Most of them will be shirtless and have a Santa hat photoshopped on (if we can't find a photo of the daily shirtless guy wearing one already). Naturally, Zac Efron is our first pic because DUH. But we've also included hunks like Chris Hemsworth and Charlie Hunnam for your viewing pleasure!

Thank us later…and HAPPY HOLIDAYS!
